Well, this looks rather...
She looks too skinny for anyone's liking, plus her legs contradict her upper body, remember, curves must be in line with her waist, they look misjoint. The main problem here is her arms, they look swollen on her shoulders, and her hands look like they've no bones within them, even arms have curves.
Try looking at a female's body, and invision her features...(I hope you don't get any awkward thoughts out of that XD)
