I think you need to work on making the terrain less flat. Perhaps some slopes, hills, and stuff like that. Some aesthetics would also be nice. As it stands, the map looks boring as hell because it's basically just rocks and land. Some structures and different scenery would be good. I suggest checking out Outbreak City. It's an excellent drive or die map that you can base your changes on.
