I've been doing lots and lots of preparatory drawings for the next book, Crogan's March (I'll probably refer to it as "March" in shorthand), and I figured I'd post a few. These are for the Tuareg camp.
Also, Atlanta cartoonist Justin Wagner's website is up and running, and he has some great sketches up on his blog. You should check it out; he's one of those guys that straddles animation and comics, and does does both well.
