I think there was real potential here, but I also think maybe you just missied . If you had been able to reflect just a little of that light onto her face and in to her eyes, and included a bit more of her head and face it would have been a great image, but as-is, it's just a little too tight & dark for my taste.
I agree with TiredIron. It's clear what you were going for and it shows that you were thinking about your shot, but it does need some reflection to fill in the shadows. Good progress though.
