I'm having a bit of trouble discerning what is land and what is water. The very pale orange is hard to tell apart from the white, which I assume is the water. I'm not sure what the light blue is on the second map either, so maybe claryifying what that is would help. My final suggestion is that you make the transitions between diferent regions more gradual.
That all said, it looks like a good start, and I'll give props to anyone attemptin to use autorealm
