I'm not certain how you wanted to capture the twirl motion is she twirling more or just about to stop going in a reverse move. I see the footwork doesn't match up to the figure's rotation. Hmm, if she is still spinning you should've just rotated her body (hips/chest) more so it matches her feet more. If she is stopping in the pose, that front foot is in a pretty awkward painful position cause of how straight her hips are. Might've been cool if you had her leaning from her hips slightly on her side towards us some due to spinning.

I think you went overboard with the cloth lines. I believe it would look alot nicer if you removed half of the inner lines and just made some where it really overlaps. Most of those minor lines would be done better with light shading, but I guess that is just preference. It doesn't really go with the figure and it looks frantic/tedious to the overall image. If the cloth is very creased/riveted you could have lines on the ends tight and then show big loose flowing slack air lines as it climbs up to the other end. I think that is what you really wanted.

Think you also wanted the wing's to be doing more. The wingspan on the right should be bent more inward on the end going in slighly tighter slanted arch on all the feathers. That end should appear clipped and cupped inward with a slight rolled arched feathers going inward.. (difficult to explain easy) But, because of it the wings look static in the picture cause they are motionless to another while their is in her figure.

Skinny females are pretty tasking to get looking excellent. I suggest you might want to try drawing bigger then you won't have much of a hassle getting hands to look good. Also, I find the neck is a tad too elongated cause she is looking down some and her neck is centered to her body line. Just if her head was leaning some it would get some more feel.

All I got to say, it's still nice overall. Hope that helps you on your next one.
