First couple of things I notice:

Those are the tiniest pointy mountains I've ever seen!
The perspective on the circular town square is a bit odd, if it were actually circular in reality it would look eliptical from our viewing position

Some houses are really hard to see and find, while the high contrast mountains and fields really stand out. Consider where you want to draw attention to, and fix accordingly!
At last, this is some very uniform color grass over all of the fields, forest and plains alike. Some variety in shade would fit, darker where there are more trees and brighter where there is open space.

They don't look very impenetrable when they are the size of a house ;)

Even then I should have been able to understand it correctly, my bad >.<

In that case, consider removing their points and highlights! And even rounded hills are larger than that :)

Palette is not so sharp, so it's easier on eyes. It's a bit noisy, maybe you would like to focus on clusters more. and make it a bit cleaner?
