She looks good to me but let me know if you think there should be any improvements or changes. When facing right, her left hand seems a little strange. Odd placement? Looks like a tail?
Edit:
Also I've noticed her wings seem to be completely translucent for her body, but not for backgrounds.
They also seem to be a bit too transparent on the view from behind, which makes it look like they're in front of her.
It might be better if her wings aren't transparent, to avoid issues like these. It might solve the hand issue as well.
I've informed the artist of both issues, but please let me know if you spot anything else strange.
