Ok, just ran around a bit so these are my first impressions. First, nice posters, didn't find them for my stuff!
Next, a few spots where there are some brush conflicts/overlaps that create transparent areas. Also in the neighbor hood are some unaligned or really out of place textures like a room with half a wall one texture and the other half something totally different from a nearby building. The only other issue I could see that created visual issues is in a few spots where what I guess is a Terrain patch that gaps from a distance revealing white underneath. Tough to catch all those buggers, but try to back them up with solid brushes the same color as the terrain. Also I'd make your shell holes a bit deeper, don't get a real feeling of doing 'into' a hole as you run over it.
Ok, BIG PLUS......... NICE frame rates! Really mid-80s to low 90s for me most of the way. You don't have too many crazy angles or funky/busy stuff going on so that really helps. Didn't notice fogplane...doesn't really need it as it's a nice compact map.
If I were to tweak it I'd neat up the brush work, add some more detail/eye candy stuff...not much, just 'deepen' the experience a bit. I love the underground lighting system, but if you add on the standard utility/coronas that will add more atmosphere at no fps cost. And I'd tweak the lighting a bit, seemed a little dark for me, but that could be just my monitor settings. Guessing it is your first map and it's pretty cool. I think some more detailing of it would go a long way. Now, build on it and see how cool your next map can be.
