First of, don't forget to indicate where spawns and objectives are, even if we can guess bombsites are the two orange rectangles.
secondly, this seems very clean, which is good. Layout seem a bit complicated sometimes, but I won't say anything more until I can play the map, because verticality often simplify everything.
Thirdly, you textured only one room, is it to test something or is it a guideline for the rest of the level? Have you some pictures in your head or as references? I ask because I am afraid you're going for something too "industrious".
Finally, if you want, you can ignore the third remark, as it is too soon to think about too much details ![]()
