Very compelling and emotional shot, I love it! Can you give the details of the shot, lighting and camera? I am an amateur and this would help me a lot.
I've begun to check out your gallery since looking at the piece I commented on earlier, and you've got some really great stuff going on here! I could be biased because this is my favorite artistic-nude pose and it's always nice when a model assumes it, but this is very nice. The black-and-white adds a sensual, warm feel to the photo and I think the model's face turned away adds a little secrecy... she's a beautiful woman and I think you've portrayed her very well.
