Here is another map called Artic.
It's a map based on a nordic/artic looking landscape and I personally think it worked out quite good.
I kept it vanilla on purpose because I wanted it to be 'realistic' somehow, but since you can walk and jump on the mountain-shade-walls on each side it eh, lost a little realism. Whatever.
There are basically 4 sides, forest look-a-like side, water side (that's the side with the most water), weird mountain formation side and the king mountain side.
