/ic/ - Artwork/Critique

Hey /ic/ I'm trying to set up a reference sheet for a character in a comic I'm working on.

If I can have some advice on 1,2, and 3 it would be appreciated. I can't feel confident at all with my quaterview and feel he looks retarded or off from the other two.

4 is the style they will be inked and 5 is a cleanest lines I've done of him.
