I like your map very much. It is very nice. I have a couple of comments thought, if I may...
First of all it's quite dark for my taste, but then again that's just me.
Another problem are the field I think. They really stand out. They should be mixed with the rest of the ground, seem like they are a true part of the land, not a paint over.
That' all I think. Other than that, very nice map!
