Very nice. This has a very ethereal feel to it. The sky is a bit of a tell that it's underexposed and not just dark, you might consider desaturating the blue a bit. Also, there's that blue-gree glow about 1/3 of the way left-to-right, and slightly less than half way up. I'm not sure I like it. It DOES lend a ghostly feeling, but it also looks like a mistake, not quite sensor dust but one of those dumb "flash lit some dust in the air" things.
I'd consider dodging it up to make it bigger and more obviously not a mistake, OR getting rid of it entirely. I prefer the former, I think, because I am seeing this as a ghostly and mysterious image.
By the way, the flower peeking out past her shoulder absolutely makes this one. Really fantastically evocative.
