Stunning shot.... The shot is the B&W.... Not even a contest...in my opinion.
My only critique would be the suit on her butt. With these suits, particularly if they are not custom suits fit to the model, you end up having to adjust the suit after the model is posed. If the suit was smooth it would be perfect. It helps to have a female assistant for these things...she could have positioned the suit after the model had posed. This is really nitpicking, but on such a great image, it's the tiny things the make perfection.
