That mid looks interesting, but the red area is a very long sightline.
Perhaps put a wall with a door so that you can break that area up into 2 areas and break the sightline?
(And, that is a LOT of red textures, perhaps add some of the whiteish/gray concrete)
r3dn4x3l4 what is that stretched looking thing in the last screenshot [bottom right]?
I still hate the second to last point but that's just my opinion and you should ignore it. Did you compile with -staticproplighting? The conpack crane looks very oddly lit.
That web placement is jarring. A web in that spot wouldn't form like that on the wood; it'd be in the gaps of the mesh, so it looks weird. It jumped out at me as I was scrolling past pictures.
Otherwise, stuff is looking pretty spiffy.
And this is the room where we store the air.
Maybe add some magical pipes or a spytech room? A balacony?
