This map is a very strong contender for "best new 1on1 map" in my mind, even though it really doesn't use the Unreal Engine's graphic potential. A well-crafted map that should be enjoyable to most.
Critique:
Once players figure the map out and the quickest ways to get from place to place, I expect to see some very, very interesting games in this arena. The layout is interesting, all 3 powerups are here but separated enough that control doesn't become impossible to retake. It's just small enough, and just big enough. A+!
