Very pretty - not that it could look any other way with this style

On the southern end of the big continent there's two parallel mountain ranges. The western one seems well enough, as it could be a continuation of the range a bit to the north, following the general shape of the continent. The eastern one looks just plain odd and unrealistic though. It runs right across the peninsula and stops abrubtly on the coasts, without appropriate island chains to indicate the ridge carrying on. It would look much better to have this second range running east-west along the southern coast of the peninsula.
