Sketch looks nice,the upper part that is.
I don't know which lines to follow on the lower part of her body?
Is she sitting or standing?
Why does she have 2 right legs?
If not 2 right legs, and if she's sitting. Why is her torso so looong, compared to her lower body?
Proportions, although in this fetish is messed a lot with, this one doesn't feel right
Edit:
Or, maybe I should google the name of the girl, and get a better idea of what she should be looking like... LOL
