@Nikolai: There's a lot of empty space and flat walls in yours Nikolai, but I like the idea of the map. Try filling some space with some trees, grass, etc... I don't really like your use of the small trees either. They are clumped and every single one is right up against a flat surface.
@Becky, your map is too small to see anything, but there is a lot of empty space from what I can see. I would cut out everything under the last house unless there is some reason for the player to walk down there, and I would try to fill up some space with plants, grass, etc...
@Shadow, looking good. The flower bin thing looks nice, but it doesn't mesh with the RTP very well IMO. Otherwise, lookin' good
