This one is my favorite so far. It's the first really unique one. The rest of the themes I've looked at are just boring layouts, but this actually adds a nice background image. Though, I think I'd rather have a border around the menus and things, just to be able to see them easier. There is just something that's hard to see about it, but I can't quite explain it any better than I think a stroke around the tables would be nice.

Anyway, good job, I hope to see more themes like this one in the future.
