Love the black and white, and I do like the concept, and the lighting. I'm not crazy about the composition; I find the model's face at the top of the frame to be somewhat distracting.
Overall a very nice image.
While there are areas which seem to be blown out, it is a very soft effect and not the usual harsh overlit look, so it doesn't detract too much.
My favourite part is the arm. If the lighting was like this across the body this would be an even better shot.
The really soft, grey tones in this are kind of nice, but something doesn't work for me. The woman's arm seems so thin in comparison to her head. Maybe it's a perspective problem, but even for a thin woman her elbow joint seems weirdly small. It probably shouldn't put me off, but things like that have an odd effect on me! The shadows are nice, and the flowers are an interesting touch.
I like it very much. Good composition and perfect in b&w. Perhaps a little burned out in the white parts but it´s just a little. Overall very good work. Good luck!
