Cute. I have issues with the seams in the paper. I've found that for shots like these the glossy side of a white sheet of poster paper works great. Just thought I'd let ya in on that tip. Cheap, yet effective :-)
Nice and creative set up. Try to have a better background. I can see the uneven edges and cracks between the sheets. Try using one continuous sheet of paper if you can, and just let it slope from vertical to horizontal position. Take a look here light box. You don't need the whole set up. If your object is heavy enough, you can place it on the paper and lean the vertical side against a wall. Also, consider getting colored paper, and try experimenting with it.
