I agree, to an extent. The shaders look pretty nice, but the texture resolution has to be much higher for it to really look good.
EDIT: Well... hm. I take that back. Everything already looks really clean and such, so I don't see what can be done there. I guess more advanced lighting effects would be nice, but they'd probably end up being a distraction over anything else. One thing that does need to be improved is the foliage, though. A lot.
