Nice style! How are you going to be using this map? VTT, printed out, projected? Detailed tactical or just a general impression of the area? I'm inclined to think it needs more pixels--it would be nice to be able to zoom in on it a bit.
The crops don't quite match--the road, buildings, and trees all have "pencil" lines, but the crops don't, making them seem blurrier than everything else.
