Hey, it's a nice little map, which guarantees a fast gameplay. The basic set-up and simple layout is perfect for teamgames.
Although I did only a quick check, I can only agree with the others concerning the middle room and about texturing. If you should open these neighboor rooms, you could implement altogether 3 entrances per little room, to connect everything with each other maybe. The texturing: yes well done in parts, but it could be better in parts also. Especially the parts where the end or beginning of a texture seems to be cut off, let some areas look unrealistic. A simple change of the offset settings together with scale could do wonders here
. I would also change and vary the texturing here and there, but the others mentioned that already. You have also room for some details, because the map runs very smooth and fast (200 fps in editing mode on my system). I would build maybe an interesting lamb or such, to use the potential. (Although this isn't a must or really necessary.) Besides the already mentioned jumpers, I like the high windows into the space
. I think this map will be great, when it's done.
