Here is a simple P&C review.
Pros:
You use the entities well, they are placed realistically; you don't just put a bunch of boxes and stuff there for no reason, you actually put the radios in the radio rooms, and proper corners, the boxes are where they really should be, and it isn't all cluttered.
However, you don't quite use enough entities. It is almost like it is abandoned. I recommend you use alot more entities, but continue your entity placement.
You use the segments well, you don't stack a bunch of walls and gantries 60 feet high for no reason, you actually build it as if it were a castle, or a fort, or a large bunker.
Cons:
Your lighting is strange, there are no sources. You use plain ambients, and that seems to be your problem. I recommend you use models for light sources, and make lights according to the light sources, and match them up.
As I said above, you place the entities well, but you don't use
quite enough. Again, I recommend you place more entities, but continue placing them correctly.
There aren't enough enemies according to the screenshots. Once again, it seems like the bunker is abandoned. I recommend you place some more enemies.
Please note, this is only off of the screenshots, it could just be some screenshots that weren't taken at the right angles.
