This is a pretty nice looking map. I like the colors that you are using, and the general shape of the map.
I don't really like mixing two different styles though. Your buildings are all top down views, while the hill and trees are all at an angle. I don't think the two styles mix well.
Also, and I don't know if this is a complaint as much as an observance, Most of the houses are pretty small when compared with the roads in the main town.
