Good idea, but not an easy subject to shoot. Kind of confusing to look at and there is something up with the focus I think, but I can't quite figure it out.
The main thing I would want different about this is for it to be sharper. There's a lot of nice texture in the pieces, but I don't feel it comes out enough.
This is a misquote, but I think the photo itself lacks. You've got some really hot spots in your lighting. And while I can appreciate a good out of focus photo, I don't see the purpose in this not being in focus.
