i have recently been playing assassins creed and the landscape on the game inspired me to make some of my own.
My idea for this map was to make it seem as if the "frost" was taking over the island, hopefully you will see what i mean. :D
things i used to build this:
world edit
world painter (first time using it)
hope you like it,
