Very interesting idea, but I think you have included too much "stuff" to be completely effective. Also, the shadow is very distracting. For some reason, the bottle and flower's shadow grabs my eye.
I like the interesting take to think outside the box. The lighting here distracts me. The image will still rank just fine with me, but the lighting shadows distract me from what the title suggests as the focus of the shot. Additionally the closed eyes on your checker queen doesn't give you as good of a shot as what you had set up.
Interesting idea. For all the set-up time involved in this, I would've preferred to see the shadows less prominent. Especially the shadow from the bottle across your model's arm. Lovely model, by the way.
The lighting here is too harsh. It is especially obvious because of the shadows formed by the flash. Try to use the natural lighting instead, if it is too dark do it at a different time of day with non-direct sunlight coming in from one of the sides. Another way to avoid the shadows is to have everything further away from the wall, so the shadows fall lower and they don't show up in the picture. Also, the checker board really blends in with the table. Try not to have so much wasted space at the top either.
