Yeah, when you specify that this happens in a place where water does not preferentially flow downhill there's not much to be said, LOL. If it's exactly what you want, I guess you got it to look exactly the way you want.

Some kind of colour/texture transition between the mountains and the rest of the land might be nice, simply for visual continuity, but I don't know squat about what you can do with CC3. And I'm not sure I can even see the political boundaries, if they're on there. A legend would be useful.

Nifty compass rose!
