Constructive criticism warning!
The proportions are a tad bit off (no fuss, anatomy's a b*tch) and the spine feels a bit deslocated because of how low the meeting point of the upper and lower parts of her back is or more likely her left hip seems absent (part of bone that "connects" the leg to the chest (side waist)). I'd recommend you to experiment more with waist and belly.
Other than that, it's a really great piece with great coloring and really smooth and pleasant to look at lightling (I'm not particularly good at those). Great composition overall.
(apologies if I came out rude, I just really like to analyze stuff)
