Casey & Hunter, as drawn by the amazing Joe Bowen! I have to post this again because it’s just too good not to share.
Joe is an amazing artist who I met on Deviantart a ways back. I really like his style—it’s dynamic and animated at its core, but full of great character nuances. Check out his site here. He did a flippin’ sweet Scott Pilgrim/Star Wars mashup not too long ago! Also, I recommend his webcomic, Model Student.
