Well, when I drew this I was origionally going to put blood (well, alien blood) splatter all over his shirt and on his gun, like he had just beaten some scum to death with it. But I don't think I'm going to ink it. I like the rugged sketchiness of it, I think it suits it. The gun is not my design; I got refrence online from Google. And the pose is based on one from the Shaun of the Dead comic (hence he took his jacket and hat off).
