Is this character from Warhammer 40K? I just assume all scary guys are from it. This really does make me realize how much your art has evolved. You are truly a professional now. With so many pictures, it's hard to not do better. I especially like the horns coming out of his chest.
They almost look like sharp nipples, ew. All the spikes are just beautifully done in this. I like the fiery background too. I guess I just assume that all places with fire are in Hell. He certainly seems to be struggling.
