for a damaged room, it looks too clean. The dirt models are ok, but the textures are to clean. YOu could put there a lot of tiny dirt. If the door was blasted there should there should be also damage around the door, like cracks in the walls and maybe black dirt. In the last shot the black shadow looks strange without a pipe or something.

The rest is looking good. Interesting project. One more thing. Closed up models like the microscope should be much more detailed.
