Hairstyle is flawless. Also, I like the decision to go without feet, keeps it a bit minimalist and evokes that this is a 'dream girl'.
The shins both point inwards... it look like a pigeon-toed stance, but the left knee isn't bent; so somehow it seems awkward. Also, you have that sexy-V crotch thing going, but the angle of her right thigh makes it look misaligned; it looks properly aligned on the other leg, though.
The torso's great with the single exception of her collar bones; they seem a bit too long and defined.Thing is, the collar bones as you have them are a head-on view, while her left arm's shading suggests that she's slightly in profile. I think if you'd just had one jutting in from her right shoulder, you'd have that slight profile you were going for.
I really like the facial expression with the wink; great job making that look natural. Winks are often tough to pull off.
If she's were real...
