This is a good concept photo.
I do get the feeling that the contrast has been over-done, however.
Violin playing (with particular emphasis on classical music), and this pose in particular, suggest a softness, which I feel is lacking.
i like this. it is a little sharp but its alright. but if she is loving music like it is implied, i don't want to know where that instrument has been. shudder. meets challenge well, good job.
Almost a pure cut-out silhouette but for the small bit of highlighting below the neck. I think that little detail makes the photo better. Very nice work!
I'm thinking you used levels or thresholds to achieve the silouette, but it's not really working for you. It especially gets kinda messy around the hair.
