I sincerely hope that the final version will not have that huge tile border distortion in your screen shots. I assume these are only shown in your map editor though.
The maps look okay, but there are a lot of empty spots. You need to fix this (not only by filling it up with tiles and crap, but also by moving the buildings closer to each other).
Also a note about your signature: a typo, powerful is spelled with only one l. But when you mean it wakes up powerfully, well, it's powerfully then. :P
Also, then should be than. ;)
