Never used the program myself, but the map looks very clean.
I would be interested to know how the town came about though, since it looks like there are 2 big lakes on both sides.
Was it colonized then a canal was built to allow ships to travel from one lake to another?
If so, you could implement a "Locks" in there, which the town would charge a tax for. Would explain how such a town is thriving without any real noticable crops in the area.
Just a couple of thoughts.
But like i said, it looks great!
