You are in need of AA bad. All of the palettes look the same, very boring. I like the overall style you are going for, it just needs more work.
Where exactly do I need the AA? Also, yea the palettes are very similar because I was testing which one fits best. The blue one is the only one I'm keeping.
I think these have some potential, I like the 6'7" character especially. As far as the shading goes: more hue shifting, less pillow shading.
Thanks. Also, for hue shifting, it doesn't necessarily make a piece look better imo, but I guess I can try it. It might add a little interest. And as for pillow shading I made sure there wasn't any, but I might have missed something. Care to point it out? Also, I tried shading from one angle or another and it looked horrible so I kept with a frontal lightsource.
EDIT: Just tried the hue shirting, really it looked worse then the blue palette that stands.
