I see what they're saying about the head (or it could be the shoulder on the left) but regardless the form works lovely for the picture. The only thing that doesn't look right on first glance to me would be the thinnest lines on the beach ball.

Nice ass, I am still practicing to do anatomy like that in my sprites... also, colors are neat, and everything else.

look at that BOOTY... and those FEET! My kinda pixelgirl

Pixelated I felt the same way about angle of the head but wasn't shure if I interpretate it right.

Obviously most of the time was spent on girl, and that's how it should be, because the rest just supports central figure. I like rendering of hair, and pretty much of everything else except mentioned angle which I'm still in doubts about (Is it possible to show face and back at the same time?) and that what sharprm mentioned. Still it's the best image of woman we seen in PJ gallery in a while.

The beach ball looks weird, and it looks like you didn't spend much time on it.

 Looks good. I think the feet look good (i.e nice and smooth), though the the big toe is on the wrong side for her left foot.

 Cute face, very well done  buttttt.... she's got ogre feet! 

Wonderful piece. I dig the style here too.

interesting piece.

another small critique: the "slam" seems to come from the wrong hand, and the feet is way too long imho

 Head's turning too far back.
