The balance feels rather delicate, threatening to tip the scale at any moment. Not sure if I like that. As a photographer, I'd place her where the image feels more 'grounded'/solid, but with her wings outstretched, suggesting leaving the ground, that may not be possible. Still, it wouldn't hurt to try moving her a bit more to the right.
Almost there to creating a 'pleasant' image -- composition is a little off. But again, it might be that you intentionally create this slight imbalance.
Other than these, composition is nice, overall.
Lighting is fine, blah blah blah, interesting highlights, blah blah blah, I'm just trying to make this critique go over the 100 word limit, blah blah blah. Oh, hey, look, it's 124 words now.
