I really like those mountains, but because they look so realistic, I would also expect the map itself to be tilted, not a top-down map. That would look gorgeous, but it would also be more work...

EDIT:

I also think that in the earlier image with the mountains on the map, there is too much separation between mountain areas and lowlands: I think it could look better if you joined them together into a single hmap > relief render (or whatever Terragen has).
