The roofs of the two front wings would look better connected as two L's I think. The main roof is quite big, it looks a little too big to me. I would be tempted to say the rear part of the main villa two story, with a single story bit connected to the other wings out infront. So that you have a seperate roof at the back and a [ `] roof plan infront of it.

The map itself is pretty awesome though. Can't fault the actual graphics any. =P
