(Before I start, the map-center thread to which I refer is found; http://www.map-center.com/modules.php?name=Forums&file=viewtopic&t=4884&start=0&postdays=0&postorder=asc
I would have posted this in the map-center thread, but I have no map-center account, and no desire to get one (As I don't want to 'Learn from the (self declared) BEST!!' :)
However, while KillZone may have acted like a cock, he did raise a valid point (as did Kell with his accusations of sycophantism, but I digress). The texturing (and to a lesser extent the lighting and some of the, interior especially, brushwork) is bland, repeatitive and overly simple.
I like the style you seemed to be going for in this map, but I think you could have done so much more with the texturing, and the brushwork probably could have been improved without hitting the performance significantly (certainly on the 'inside' areas of the level).
I find that it just makes the map feel unfinished and rushed.
(All this of course is entirely separate from the gameplay, which I do like a lot :)
