Kolari, I really like DE_Tibet. Sorry I climbed on the roof.
Clipping issues aside, the layout made a lot of sense to me. I think the mountainous skybox helps to orientate the player in the world, so it was pretty easy to learn and navigate even without lots (or any? I forget) of signage. The only frustrating point for me was the CT approach to bombsite A (I think ... the one on CT's left-hand route?), which either needs more cover for the CTs as they come out of the little house, or a quicker way to counter T's rushing by lobbing grenades over the wall.
Cincinnati, I realise you're not looking to change much geometry-wise in de_disruption but there are some big improvements you could make with minimal effort:
-Block off the long dead-ends with fences or something. Namely the long corridors near the underground bombsite. Not only do they give attacking players too many dark corners to check, first-time players will always be put off by having to turn back on themselves to return to "the action".
-On the big staircase with the orange walls, fix the B arrow that points the wrong way. I get that it's a passage that's been narratively blocked off so in the real world the signage wouldn't just disappear, but it's frustrating from a gameplay standpoint.
-Make the strip lights in the underground bombsite in to func_illusionary or clip them off so that defenders can't perch on them -- it's just one more awkward place to check in an already complicated space.
-T's start out in that really long canal path followed immediately by another quite long sewer path -- maybe break them up a bit with some more corners so that it doesn't feel like a really long trudge.
-There are lots of neat little holes to shoot people in other areas from, but perhaps a little too many. Options are great and all, but it will always feel unfair to get shot by somebody you have barely any chance of seeing. The most irritating one for me was in the afforementioned big staircase, a little square window on the right-hand side as you go up. The one at the top of the stairs leading down to the outside bombsite seems a little unfair as well, especially given how far away it is from the areas it covers.
