I agree with Youme, seeing a little more cliff detail might be cool.
One of the small red buildings (angled) has angled floor tex, all the other buildings are straight.
I saw z-fighting at bottom of spiral ramp, the brush under it shares the same front face area.
I've been playing this alot, no complaints, one of my favorite arena maps hands down. Lumberyard is my fav valve one, this is right there. Then I like badlands and ravine. So it's better than most Valve arena maps IMO.

Oh, today while playing i saw a scout up in the top spawn room window, think he double jumped up the shelves.
Probably need to clip those trims.
