I think you should find a middle ground between the too many colors version and the current version. Specifically, the body and face of the new version looks way better, but the highlights in the hair on the version with too many colors look amazing, and really compliment the chibi-anime look, so I would keep them.
Your idle looks pretty good, but I have a slight problem with it. Basically, the hair torso and arms appear to be slightly rotating, but the legs and face dont. My solution would be to either loose the subpixel work on the hair, and just make the head move back and forth, well changing the legs slightly to make it look like he is shifting his weight back and forth, or make the legs and face rotate along with the rest. If you go that path, slight rotation on the legs/hips and more rotation on the face/head.
