I really love the way the map looks, and it seems balanced for the most part, but there is one crucial flaw that I see: Red player has WAY more lumber in his base, while blue has to "expand" north for lumber.
Also, the bases could be walled off by using the town hall as part of the wall, but there is not much space left behind the wall to build Tier 2 buildings, especially for elves, who have to eat trees to make space, and again, in the blue base there is water where there should be trees, so no expanding your base towards the edge of the map like red can.
