I think you went a little overboard with the contrast, but I get the idea.
Edit:
I don't think it was my colors(though I did mess with them a little), so much as me using them inefficiently.
Removed the action lines. They served no real purpose.
Changed the mouth to my darkest color, but pushed it a little green so it wouldn't look out of place in his mouth. I left it in the same ramp, though, since I'm still using it as a black.
Also, added another shade of grey, but It's the same shade as the background, so I just left a hole in the ramp to denote that.
I feel like this one is
way better than my last try. You have been most helpful, Mush.
