yes, that definatly looks lots better, still, there's things to change ofcourse but we are here to help you out ^_^

first of all, the wires, you are allowed to have more faces in there to make them look less edged and more rounded :P scale them down as well, like half the size it is now.
second, what's the white thing? again looks too clean, and kind of doesnt fit the environment, might wanna remove that, and put a broken panel model on the floor below the hole...
the roof definatly is improving, but scale it a little smaller, it is just TOO big now (like, between the current size, and previous size).

though the walls have been improved, rather then just blending it black, try adding some more "gross" things there, brown/green spots in general do well (again, can be solved with simple sprites, but make the transistion as less noticeable as possible there, as if the ceiling blends the walls, which blend the floor, that should be best for horror levels!).

doorposts look way better now!
and the fire exit is a cool addition

the pile of dirt in the background looks way to big imo, might wanna change that for (again) a sprite with a texture on it that's worn out, if you have no clue on how to achieve that, i can make you one, so you can test with that a bit.
and again, in general, add more dirt, that's the clue

great job so far, and keep it up! love seeing this develop.

regards,
