I like the base concept a lot, the lighting is good showing the skin texture.  One part to consider if shot again is to move the arms out of the photo, they add nothing to it and detract from the lines.  The arm in the back sort of mutes the body line and the one in front adds an odd angle to a tiny corner of the composition. 

Another suggestion after looking more is to find a way to tone down the edge of the highlights since the skin is so glossy.  I can easily pick out the edge of the box-light or window used, bit of a harsh edge to the highlights, maybe a diffuser or an umbrella might help in toning it down a bit.

If this one - https://www.modelmayhem.com/portfolio/pic/46529429 was cropped similarly I think it would be stunning.  There is no distraction to the bodylines and the highlights flow nicely over the subject.

Just my opinion!

Thanks so much for your thoughts. I really appreciate it.

I like the concept.
However this one is more powerful:
