Everything the others said and I'd make the lake look like it was more in perspective so it's consistent with the rest of the map. I much prefer the map without the green (which is too saturated for my taste). Some variation of the tree symbols would be nice too. I don't know what the map is for or whether it's for print but for the sake of aesthetics I'd make the animal prints smaller. If you are going for the montone look, I'd lose the the blue for the water.
