It's all right, but I think you rely too much on scenery and don't have much strength in polygons and vertex-colors from what I can tell in this map. The layout is also too mechanical and flat, especially for a DeathMatch. I would normally object to posting with the objects shown (or at least, without an alternative overview which hides them), but the screen shows collider-walls, so I'll let that pass since I've something to remark on that; I think it would be better to have only-bullets-collide polygons there instead, unless you purposely want grenades to explode upon impact at those areas, since OBCs at least give a chance for very fast bullets to pass through.
I like the use of scenery and double-texture, but I highly recommend first thinking of a good map layout to start with. You may also want to study the default maps or others' maps here to get a good idea on how to set good polygonal colors. Keep working!
