ok so yeah its a tundra but i still think some more detail than that is needed. a few cliffs some elevation with hills, and some ground detailing would make it look better.
also WTF is with that 3X3 block of green in some of your newer pics......it looks really out of place
also i think you could put some invis light posts inside the small towns and some alpha light posts here and there in the towns to. and i dont really like that random purple/red on the hill area there although i guess that is where the map gets its name? i think the "starlight hill" should be on top of a cliff and should be a big hill and not some small thing maybe i think that would spice it up some
