The strange upward swivel of the hips, and the lack of shoulders ?
Plus her breast is making a break for it...

However, nice tones, and sweet features.
No consistency in angle of perspective (the bed is different from her body) and a failed attempt at foreshortening are the biggest things that stand out to me (which cause some of what you highlighted).
Totally agree though, the skin tones and lighting are crazy good.
