cool idea. Lighting should have been more thought out. try using a light source other than your flash. a small lamp to the upper right of the hands would have worked, and the table is not a great background.
I really like the warm tones. I think the next thing I might do is to try to get the lighting to be more even. Paper is maybe just a bit over exposed and the others are edging into under exposure near the edges. A second or third light source might help that. The yellowish reflection just over the rock is distracting. I gave it a 6.
