Saxon & Kenzie

This is a colored version of an inked piece I did (long enough ago I can't remember if it was just for fun or a commission).

I enjoy getting a chance to go back and color these to add some more depth and clarity while also hopefully making some new process blogposts for you all to see and eventually to be included in a new sketchbook (though I just released on this summer: Axe Wielders which is still available for sale)

Below is the process for creating the illustration as well as coloring the artwork.

Pencils:
The start of this was done as two separate drawings on different sheets of copy paper of both Saxon and Kenzie. Those were scanned and tinted different colors in photoshop as I digitally blocked in a tree and some leaves (and digitally added some bark detail to the tree). The grass was it's own layer where I had an outline so that each blade of grass I drew already had a hard line around it for clarity. Oh! and I dropped in a 3D model of a sword because I didn't draw one beyond a directional line in the pencils

Working like this allows me to still draw some on paper while also getting the resizing and editing benefits of digital.

Inks:
With the layout complete, I printed it out and taped it to the back of a sheet of Strathmore 300 series bristol. On my huion lightpad I was able to see through the surface of the bristol down to the printout to use as a guide as I inked. I inked this with Copic Multiliner SP pens (the 0.3 & 0.7 nibs).

Most of the 'work' in this piece was in the texture of that bark and trying be sure it wasn't overwhelming and had some depth while leaving the forms of the characters clear.

Color Flats:
The first step of digitally coloring a piece is do establish the color areas with flat colors (a professional version of coloring-in-the-lines). Most of my color choices were already established with the characters themselves and the layout, but I adjusted them at this stage to make the piece more cohesive.

I also established color holds (areas where I want the inked line art to be a color other than black) on the background grass and the leaf veins.

Final Render:
The rendering was all done with the dodge and burn tools in Photoshop with a stock textured brush.

Here my trickiest part was getting a sense the light was coming in from the right on the character as well as a the leaves and the highlights on the bark.

This piece will be included in the next sketchbook out sometime in 2026!

Mouse & Magpie Illustration

This is a colored version of an inked commission I did for a fan a long while back. The idea was a mouse horder/collector (insert pack-rat joke here) along with a magpie companion.

I enjoy getting a chance to go back and color these to add some more depth and clarity while also hopefully making some new process blogposts for you all to see and eventually to be included in a new sketchbook (though I just released on this summer: Axe Wielders which is still available for sale)

Below is the process for creating the commission as well as coloring the artwork.

Pencils:
The start of this was done as three separate drawings on different sheets of copy paper. The mouse was drawn first and the magpie was drawn using photo reference. On top of those sheets on a lightpad I drew the mouse's collection of goods. Those elements were all scanned and tinted different color in photoshop and moved and re-sized until it fit well inside the square border of the piece. A quick amount of tan digital painting was done to imply the areas of the tree background and the rocks and stick debris in the foreground

Inks:
With the layout complete, I printed it out and taped it to the back of a sheet of Strathmore 300 series bristol. On my huion lightpad I was able to see through the surface of the bristol down to the printout to use as a guide as I inked. I inked this with Copic Multiliner SP pens (the 0.3 & 0.7 nibs). Since this original art is what the fan who commissioned this piece will own, I always want the art to be crisp, clean, and detailed enough to stand on it's own without color.

The original was then shipped off to be with it's owner, but not before I got a good scan of it.

Color Flats:
The first step of digitally coloring a piece is do establish the color areas with flat colors (a professional version of coloring-in-the-lines). Here the final color palate isn't as important as being able to easily isolate any part of the piece when it comes time to render it (like being able to grab just the mouse's fur or just the cooking pot, or the sword in the magpie's beak, etc)..so while I got the backgound and figure colors close to final in this step, with all the bits of the mouse's collection overlapping each other, I needed to abstract that and just do vibrantly wrong colors to be sure I got everything and enough separation between them all.

Final Render:
I'll admit, this piece was hard to manage so the viewer could still focus on the characters while being able to get lost in the objects. The rendering was all done with the dodge and burn tools in Photoshop with a stock textured brush. I forgot to mention on the step above, I added a color hold (where I want the ink lines to be a color other than black) to the trees in the background as well as the ground as it recedes into the background on the left.

This piece will be included in the next sketchbook out sometime in 2026!

 

Dawn of the Black Axe Hardcover

Dawn of the Black Axe, the three issue Mouse Guard mini series about the first wielder of the Black Axe is coming out in hardcover in early 2026. The miniseries was written and colored by me and drawn by Gabriel Rodriguez (Locke & Key).

To Pre-Order: https://www.penguinrandomhouse.com/books/813486/mouse-guard-dawn-of-the-black-axe-by-david-petersen/

For the hardcover collection, I did all of the book design and asked Gabe to do a new illustration for the cover. Here you can see the final cover design, but below I'll walk you though the process Gabe & I went through to create it.

I sent Gabe some reference and a sketch of the type of image I though the cover needed. Specifically Bardrick with the Black Axe (referencing an old print of mine and a panel of Gabe's from the book) along with the concept of some kind of knot of the five snakes behind him.

Gabe was worried about making the background too chaotic and unreadable and opted for a more geometric and stylized version of the snakes (he told me he was inspire by Thulsa Doom's symbol from the Conan movie). Here are his pencils:

Gabe then inked the artwork in his expert way of knowing how to play with line weight and pattern. And he sent over a high-res scan. 

I then did the color flatting on the piece establishing flat colors for everything and also creating color holds (areas where I want the linework to be a color other than black) on the snake circle and then on all of their eyes. Most of the color choices were established in the issues already I needed just to sample them.

The final colors were done using the dodge and burn tools in Photoshop to render shadows and highlights and add some texture with a stock brush.

Recent Sketchcover Commissions

Here are some of the recent Sketchcover commissions I've done at Heroes Con & SDCC

Lieam with the Black Axe

For my new Sketchbook 'Axe Wielders' I created a new illustration of Lieam with the Black Axe and a runic 11 (as he is the 11th wielder of the ancient weapon).

I know fans have been long waiting for a story that takes place after the Winter storyline, so seeing this illustration of Lieam must feel like a tease, and for that I apologize and thank you for your patience.

Below I'll share the process into making this new piece of art for the sketchbook about all the past wielders of the Black Axe.

It started with a loose sketch of Lieam with the axe that I scanned and color blocked in Photoshop. There's a bit of a homage here to Sean Rubin & Alex Kain's Legends of the Guard story, so I then looked at a lot of photos of bears until I found one that would fit where it looked like it was behind him, but also shrunk down enough to fit in the frame.

I did a draw-over that photo to get a pencil version of the bear's key points I needed to include.

As you can see below, I opted to cover over much of the bear with a stone den opening and also included ferns (barely visible here).

With a printout of the above rough (and perhaps a bit more work done on that stone den and fern leaves) I taped it to the back of a sheet of Strathmore 300 series brisol. On my Huion lightpad I was able to ink the piece seeing through to the printout to use as a guide. 

I used Copic Multiliner pens (the 0.7 nib mostly) to ink the piece. With all of Lieam's bracken cloak, lineweight had a lot to do with making sure the image was readable. I also used more texture on the fern leaves to help differentiate from the more open bits of Lieam's cloak and the bear's fur.

When the inks were finished I scanned them and started the coloring process. That first step is all about establishing flat color areas (known as flatting) with no lighting or texture. A professional version of coloring-in-the-lines.

Most of the color choices were straightforward, though I did have to play a bit to get something that worked in color harmony as well as value-play.

At this step I also established color holds (areas where I wanted to linework to be a color other than black) and did so for the runic number (and later the bear's eye)

Here again is the final rendered artwork included in the new sketchbook.

The colors were finished using the dodge and burn tools in Photoshop with a stock textured brush to add shadows and highlights.
