Suggestions:
1. Make a large slow moving door or somthing where the vents end and the "storage area" begins. Right now its alittle "unrealistic" to have a huge vent just open up as a walkway into a diner... wtf?
A huge door (mabey able to open and close only by press of a button next to the door?) and some other vents to "vent" the air into the underground levels would looks much more belivable. How about have a small vent in the upper-middle of the door that "vents" the air (also serves as a conveinent walkway for dretches and jets), while the slow-moving door surrounds the vent in the upper middle of the walk-way. Button operated hopefully
2. I still think the undergorund should have less "ambient" light levels. The diner and UFO room is good i think. But a large room like the M room, and the bottom of the elevator, and a majority of the hallways i think have too much ambient light for an underground area.
Im not saying to make it really dark underground, just make it look alittle less daylight looking.
