I'm backing up RP's assessment, Keith: the colors are much more pleasing to the eye, and the grass/fields are awesome. But the buildings are too blobby; IMO worse than the original--although I see why you changed the style to fit the new map. I wonder if sharpening as you've said will help--as well as doing something so the roads do not seem "floating on top of" the structures vs. between them on the ground? Shadows and such would help, as would blurring the roads. A similar situation occurs with the walls & towers: they are still too vector in my mind to fit the more organic style of the rest.

Just some ideas, Keith. No matter what you decide to do this will still be an amazing map!
