Really nice! The only problem I see with it is that her left hand is wildly out of proportion compared to her right hand. It's not that noticeable but since I've been taking anatomy and proportioning classes in college the past two years, I couldn't help but notice. I think if you made the left hand a touch smaller and the right a touch bigger you would have the hands completely perfect!
The only other thing is that her hair isn't moving but the rest of her clothing is, that leaves the viewer to think that her hair must be extremely heavy, but I love the design and how beautiful your values are
You really captured a feeling of movement in this figure, it feels almost as if she were dancing! I love how you have no heavy lines. The only thing I would have changed was how static her hair seems as compared to the near liquid flow of her clothing, it seems as if it's heavy or weighed down. Your use of soft shadows is very convincing. Good job! ^_^
