I agree with JBinc :3 His pose is a little stiff perhaps if you tilt his shoulders back and chest out with his hands on his hips, it would certainly give him a defiant and bad ass attitude lol you'd need to be crazy to wield a gun like that (is it a gun? must be a gun Xp)~ but that may depend on what your character is like X3
His clothes are cool and the shading is nice too, if you got anymore sketches post em :3
