off topic: could you try putting lava in the volcano and adding grass?
on topic: I checked out the map it seams a good size, the is beach cliff is really cool, I haven't checked out how good it is for building (I'll do that later), could use a bit more beach (but not too much just like enough for a small house), and needs a tree.
From my review I give you..... 4/10.......... it's O.K.
