You'd be well advised to scale the hill brushes 20x20. 1x1 is insufficient for outdoor areas. Why am I saying that? Look the the repetitive pattern back right.
Other than that you've got certain sets of the hill textures at your disposal yet you seem to relay only on 1 single texture. Mix em up.
Other than that I'd eventually add an opening somewhere onto the hills and place some building complex inside the rocks to make it look lesser like a square. Either that or add some models like antennas near the hill edges to provide the illusion that behind the hills the landscape continues.
