i can see what it is about the image, lighting set a perfect mood for her demear .. with that type of natural lighting i would see it more as a b & w, great fine art photography.
you'd be a big fan of this Canadian reality tv show, "Naked in the House" One camera. One lens. One roll of film. One half hour; to shoot one nude model. they select several photographers to get that one shot in 30 minutes without any set up or pre production.
