whats with the lighting on the arm? In reality the face and the hood or whatever u call it would be blocking the light from the arm. I FIGURED your light source is on top so...... idk but it looks great, your insanely better at this then i am. but the lighting on the arm is weird, but it looks great and some of that looks embossed lol
Edit: Maybe you could use dodge tool to make the red eyes a bit brighter or whatever they are
