Put it in rotation on the beta server. Looks pretty cool.
On the windows, you should cut out the brushes and make them flush with the wall. This will look better, prevent the edges you can get caught on, and reduce r_speeds (the walls will be split up by the compiler anyway). Where did you get the textures? Is it possible to use higher quality jpeg compression on them? The artifacts are visible (especially on ground_01). On the parts that are open to sky with other parts of the map visible through the sky, you need to either build the wall up higher (so you can't see through the sky), or build the map out but clip brush it off (so it looks like the building goes out and covers up parts you don't want people to see through).
