The newest one looks really really good.

Enough green to satisfy me personally, although I'd maybe implement some forests. The cities look brilliant, would you mind telling me the hex-data for the color used? I'd like to try that one for my planetary map, too, if it's okay with you.

Also, you might want to add some rivers maybe? Rivers and woodlands would make this planet a lot more diverse and awesome, I'd say.

Also a last point of criticism: Put a very few lights inside the continent, or at least a little deeper into it from the sea. The land may not be settled much, but - without further knowledge - I'd say there would be several locations on the "inside", too.

Hope this helps in getting this supreme work a tiny bit better! ;D
