This needs a lot of tightening up.
* First of all, she doesn't have enough leg for her torso.
* Arms are very vague and do not suggest the forms you'd expect for forearms
* Shadows in the lower legs seem to suggest she's bending her knees, and along with the short legs this conveys a pretty uncomfortable position.
* Boobs are kinda gigantic, also have no nipples.
* Face is very ambiguous with the pixel clusters there, needs a lot of cleaning up and more symbolic representation I think
* Latest edit reached a color count that this piece so far really doesn't need.
I attempted to address a lot of the issues and I spent a lot of time making a soft palette that suits this, along with contouring the forms with shadow and light... a bit... fetishistically, so excuse that perhaps. Curves of belly, knees wrapping up, venus mound, the forms of the leg muscles, these things can still be conveyed with some grace at this size. Also clavicles, arm shape, generally, more anatomy.
Another big thing, be careful with such huge hilight areas in such a small piece, you're completely drowning your middle luminance, which is what should be used primarily to convey the flesh. At this size and in most moisture/lighting conditions, highlights should be reaching two pixel or one pixel speculars more than anything. Convey forms with softer palette entries that are subtly lighter than main skin tone, not with HUGE WHITE BLOB OF HIGHLIGHT ON LEG AND BOOB, if you catch my meaning.
Hope I helped.
