This is awesome dude! I never knew you were the one who drew these covers! I'm working at a studio that's putting together the ComiCon trailers for the new Radical comics, and we just finished the Caliber one! If you get a chance to see it, I'm the one who did the puppeting of the artwork. Let me know what you think!
The colour contrast works but the chap at the top has more facial definition where as the other figure looks a little stiff and posed...It just throws this a little off kilter for me but I do love the tree detail (yes an odd thing to pick up on!)
