Many rendering engines (and some modeling programs) don't display the backfaces of polygons, hence the tree leaves not showing up on the bottom. You're welcome to tweak the model for your own personal use, however, this is not really a problem with the model, and I recommend using the unmodified mesh when you submit them. For programs that don't hide backfaces, having two polygons in the same location causes unsightly rendering artifacts, and separating them can be a real pain.
Anyway, the models look great, and I really look forward to seeing these submitted!
