I like it! The things on the roofs of the small houses seem a bit over the top, hence them being small houses. Try adding a bit of depth when making small lakes and rivers.
I was going for something a little off but with a charm, for the roofs. Lakes will obviously dug out since I was just marking the area for it at the time, but I will probably get to that last as I plan to finish all grounds.
Nice job! I'm creating a huge map for a game I created, its going to take a month or two to complete :(
