I really like the palette but as a whole it just doesn't seem to gel together like your maps usually do. I think the main reason is the way your elements don't feel part of the map but just placed on. For instance, your mountains show the colours coming through, which is ok, but when they go across several colours they betray their PS brush origins. One of the mountain peaks goes over a lake and the blue shows through the same as the white does elsewhere. Also, your TreeThing forests seem to lack any jittering so the trees are placed in digital lines that really stick out.

Sorry to be the dissenting voice here, I wasn't sure whether to post or not but then I asked myself, would I sooner someone posted an honest opinion on a map of mine or just keep quiet so as not to hurt my feelings and let me go on believing it was loved by all?
