I see you went for a more cohesive texture style this time - presumably to make the map look better under QRP? - but the result turned out somewhat monotone and gray. It might help if you had more city2_6 trims everywhere.
The checkered floor texture clashes with the metal walls badly, IMO.
The lights on the stairs didn't look too good - either use a smaller light texture instead of resizing the large one, or shrink the floor texture.
Like negke said before, the teleporters felt unnecessary, and could as well have been jump pads, or lifts - or maybe even some E4-style stairs. Also, the actual teleporter seems a little
too big.
This area seemed perfect for a powerup (maybe a MH?) but I dunno if that's a good idea for a 1v1 map.
