I like the look, generally, and the burnished metallic skin is pretty nice. It feels like you've pushed something a little too far, the highlights on her skin feel a bit flat.
I'm assuming it's meant to be a dark image both in color and in representation. Assuming that's what you intended, it's an awesome image and I'll bet your audience loves it. Beautiful model by the way.
I have not done any floor work with my subjects yet...this series reminds me I need to. Usually I put them up on a table and pull the backdrop over the table for the lying poses....but I think I need to put a few actually on the floor here soon.
