Lol, was it really necessary to necro the thread for this?
Anyways, might as well give some criticism.
The river looks unnatural with the 90 degree angle.
I know it's nature and it's supposed to be random, but the trees and foliage are messy and the map is too cluttered, maybe try to make groups of trees instead of spacing them apart like this.
The rocks or something in the river look out of place.
im missing some variety in the trees, only two trees is not enough IMO.
Those are the things that spring to eye immediately to me.
Good luck!
