1, It is? He is actually furthest away from the table so making his head bigger would look even more weird. The reason I did that was because I considered him to be the one who runs things in Madness.
2. Had a couple of comments about that. Guess I could have added him instead of the grunt, but I really wanted the grunt in there somewhere and that was the only place I thought of adding him. Couldn't move him to the right because that would throw off all the groups of 3's in the scene.
3. It was originally gray, but I made the edges dark so now his shirt looks black.
4. Doesn't have a halo in the series or in this scene? The halo is the white ring around his head. In renaissance paintings, jesus usually has a round gold circle behind his head (actually a cross nimbus). As for the suit, I probably should have eased off on the shadowing. Giving him a whiter appearance would have worked better for the composition
5. I was mainly drawing everything from references I found online, and those zombies had shirts on.

Thanks for the critique
