The problem that I have is that the mtns are all the same height in appearance and the escarpment doesn't seem "cliffy". The challenge map that I did last year didn't exactly nail the escarpment either. The forests are kind of blobby - they start and stop quite abruptly with a solid edge. I'd add some solo trees around the edges or somehow "dither" the edges with chunks of trees. On the whole it seems rather flat except for the trees and mtns sticking up and dominating everything but it's your baby and this style seems to call for that kind of thing, shrug.
