Overall a nice job. I agree with Max about the proposal for adding drop-shadows on the trees though; it would increase the consistency of the map. In addition, I would add that the forest, woods or copse to the north east and along the shore of the river on the northwest are a bit sparse. If you add in several different layers of trees (the top layers overlapping the bottom at some points) and add drop shadows to each layer, soon you will have the simulacrum of a nice wooded area. Oh, and nice job on the hand-drawn houses!
