Dawn of the Black Axe Print

The Mouse Guard: Dawn of the Black Axe hardcover is OUT TODAY!
You can pick it up from your local comic/book shop or various online retailers (https://www.penguinrandomhouse.com/books/813486/mouse-guard-dawn-of-the-black-axe-by-david-petersen/)

I entrusted Gabriel Rodriguez with the visuals of my world of mouse adventure as we told the story of Bardrick, the first Black Axe and he did nothing short of a masterpiece of illustrating.

I'm offering a 8"x8" print in my online store mouseguard.bigcartel.com I drew of Bardrick with the axe and the five snakes who surrounded all that was. Below I'll walk you through the process of creating the artwork (and another bonus FREE papercraft at the bottom of the post)

The piece started with rough sketches for my ideas for Gabe to draw for the hardcover collection's front cover. It was based on my original drawing of Bardrick (in the Axe Wielder's Sketchbook) and a panel Gabe had drawn in the issues. The concept of the snakes as a celtic knot appealed to me to tie into the illuminated manuscript illustrations I typically use to show Black Axe history. Gabe's cover certainly has this vibe and tone, but with his own sensibilities in his own artistic voice.

Something about that loose sketch with the more tangled snake knot wouldn't let go of me. I wanted to see my version of that drawing to completion and figured if I offered it as a print, we could put it in the online store and take it to conventions. I tightened the pencils of Bardrick on one sheet of copy paper (lightboxing a blowup of the original loose doodle)

Then over the course of several sheets of paper and digital blocking in of colored stripes overlapping each other, I was able to do tighter stylized versions of the five snakes: Gammeltan, Dødfare, Skalaknute, Streikrask, & Langtspyd where I tried to infuse details into their patterns that are special to each snake's appearance, build, and abilities.

The layout (a combination of pencil drawings and digital compositing and color blocking) was printed out and taped to the back of a sheet of Strathmore 300 series 12"x12" bristol so I could ink it on my Huion lightpad.

I inked this using a Copic Multiliner SP 0.7 nib pen. On the lightpad I'm able to see through the surface of the bristol to the printout to use as a guide as I ink––which means no erasing away pencils or digitally adjusting away blueline.

Even though I'd done so much prepwork on the snake designs, keeping all of the patterns and lineweights and details on them straight as I inked around Bardrick was the trickiest part.

When in the inks were finished, I scanned them and started the coloring process. That first step is called 'flatting' and is basically establishing flat color areas for each part of the illustration. No textures, no lighting––just flat base colors. Much of the color choices were already established either from the comic issues (which I colored) or my rough starting sketch...though lots of the colors needed little adjustments for hue, saturation, and value before I felt like I had a place to start rendering.

It's also at this flatting stage that I established all the color holds (areas where I want the inks to be a color other than black) on the snake outlines and their inner details.

Here again are the final colors all rendered out mainly using the dodge and burn tools in Photoshop to get all my shadows and highlights and the textures are achieved by using a stock textured brush in Photoshop.

The Hardcover book (out today!) collects all three issues (including all the variant covers) of Dawn of the Black Axe, and this print is available right now as well in my online store: mouseguard.bigcartel.com

Also available for FREE is a PDF print & assemble papercraft of Bardrick I designed on the Mouse Guard website:

Lieam vs the One Eyed Owl

As I work toward a new sketchbook in 2026, I'll be doing a series of posts about Mouse Guard illustrations I've done that will be included in that new release: 'Past Whereabouts' that will debut at Emerald City Comic Con and be available in my online store soon afterwards.

Sketchbook illustrations are often a chance to explore corners of Mouse Guard that I haven't gotten to yet. Whether it's certain locations, characters, or just ideas or thematic tones. For this illustration It's the scene from Winter 1152 with Lieam vs the Owl after Celanawe had fallen. In this post I'll break down the steps to creating the illustration

Since the title of the sketchbook is 'Past Whereabouts' I thought it would be good to revisit some familiar scenes or locations. This moment (I'm sharing almost on the dawn of a new year) is about the loss of something (Celanswe) that also gives new life to the future (Lieam as the Black Axe).

I drew the owl separately from the mice each on copy paper and then scanned them and digitally blocked in color to help establish the forms and to figure out the landscape.

The digitally assembled pencil layout was printed out and taped to the back of a sheet of Strathmore Bristol and placed on a light pad. With the light shining up, I was able to see through the bristol surface to the printout to use as a guide as I ink the artwork. I used Copic Multiliner SP pens to do the inking (the 0.7 nib mostly)

In revisiting this scene I handled the inks on the owl feathers a bit differently than before, bit for the most part the stippling of the snow, the silhouettes of the trees, and the details of the mice were inked the same as when I inked the last pages of Winter.

Next step was to start the digital coloring. After scanning the inks I painted in flat base colors––a professional version of coloring-in-the-lines.

Most of the color choices for the characters were established in the Winter book as well as the rough layout. These colors needed to be color shifted cool as well as muted and desaturated.

It's also at this stage that I established color holds (areas where I wanted the lineart to be a color other than black) for the snow, trees, and blood.

The last step was to render the colors with dodge and burn tools and a stock textured brush. Dodge and Burn are tools based on photography terms (and from when Photoshop was a photo retouching program) having to do with purposely over or under exposing areas––or in other words darkening or lightening them.

I use these tools to create shadows and highlights to my base colors while giving a bit of a pebbly texture with that stock brush.

This illustration, along with many more, will be published in the sketchbook 'Past Whereabouts' which will debut at Emerald City Comic Con in March 2026 and will be available in my online store soon afterwards: https://mouseguard.bigcartel.com/
