This is a beautiful shot black and white image. The lighting is done in a very classic style with shadow and light. It is exposing the body and face just enough in a very sensual way. Great detail in the skin from the feet to the face. Also like the back light/side striking the hair and face.
My only comment towards correction is i would have liked the curtain in the back to be less noticed. It pulls the eye to the back a bit. If it would have been over a bit it would not have the effect of cutting through the image. Putting it off to the side and more in the shadow would distract less from the figure study.
Great job on the lighting and image.
