It seems kind of cube-ish though. And it isn't nearly as detailed as your previous desert2. The textures are bugging me though... the gray brick roads?

This is pretty good map.
when I played it with you, good job!
But I already have a map in my library called desert3(made by someone else).
So maybe you should change name. :)

There is very little detail and perhaps the openness is not as good; I like ac_desert where you can run like in a maze and knife enemies and such :P
Too much open space will make it like depot in big games - very very hard to play.

The blue light is a bit strange to me - haven't seen that before, really.
But seems quite good.

Better than most of the crap put up for ac ;)

Haha..

But the blue lights are a bit wtf.
And the position of the engine box seems weird.
And on the ceiling somewhere, along one of the beams (i think it was next to the power box) there is a small error caused by a corner (k).

There are a few mistakes here and there, but when those are fixed I would really like to see this map become official.
