I think you pretty much nailed all your goals
Yours is incredibly popular map on this server and very fun to play. The only reason I rebuilt it was for the frame rate issue and maybe I did a bit too much tinkering with it along the way.
As for the inside of the Parthenon where did you get the floor plans from? I understand it's meant to feel huge but I just get a weird feeling that on the inside of it that things are out of proportion. If it had two floors on the inside I think it would feel ok. I don't know if I've mentioned it before but I suffer a bit from Alice in Wonderland syndrome (lol I know) and If I play those rat maps or things are too out of proportion I get headaches and I have a sort of hypnotic effect where I just stare at one point of the screen and don't see everything around me (so I get shot). It's a weird and very specific complaint but, yeah, that's why I don't like textures being stretched too much and things like that in maps.
Out of curiosity do you have any other maps cloune? And how long did parthenon take you to make?
