This is the wip for the characters that are going to be in a platformer game that I am working on. The protagonist is facing right, enemies are facing left.

Old walk, Im going to change the arm and shield/sword movement a bit:

The version of the protagonist farthest left was the sloppy mockup version. When I decided to try to limit characters to three colors, I had trouble making his hat fit in, so I ditched it. I feel like I had some success with readability but he still seems very flat to me and any color recommendations would be appreciated. You don't have to stick to my restrictions with c&c but I would prefer if I could stick to three colors max per character.
I feel like i had some success with the knight, but the axeman seems a little off and again, kind of flat. The skeleton is more wip than the rest and is just a sketch, but any help with him would be appreciated as well.
