Well seen, but there is a tonal merger between the right nipple and the background. Don't know if this is a scanning issue or not. It's distracting in that something you expect to see is not there. The other area for improvement is the position of the thumb on the right hand. It is a little distracting. I have always thought that nudity begins with the hands. The position of hands (and fingers) is very important in figure photography.
Thanks Joe and John for commenting. As a consequence of your comments I posted a different image from the same session, that is a variant on this theme. I would be interested in your comments on that version. I actually liked the chiascuro (sorry, I can't spell it) effect of the image blending into the background).
