I agree with JB, making the forests ascend to the base of the mountains was a really nice touch. And, as always, really dig the style of those mountains.

RazielKilsenhoek has a point about the clarity of the fonts on the mountains and coastal cities. I agree that this problem might be side-stepped with the coastal cities by simply changing the color on the labels to a lighter hue. As for mountains, I've run into this same problem myself and am still casting about for a decent solution to it, so I'm afraid I don't have any recommendations for you there. Great work so far though.
