To me this is the most appealing port visually-wise (so far).
According to the former screenshots I'd reduce the brightness of all lights, maybe even add some flickering ones to increase the immersion.
Furthermore, in KF1 the ceiling lights where placed behind most of the ceiling decoration (those pipes and vents, etc); this resulted in shadows being casted down to the floor and walls which helps to avoid them from being equally lit all the way down (a big thing when I compare those maps).
The high-tech doors somehow do not fit the scene that well imo, especially when mixing them with conventional doors in the same hallway. Imo, you should decide for one of them style-wise.
The first of your latest screenshots shows a scene with three "hard" colors (red, blue, yellow) mixed together without any gradients. I'd suggest to tone down the saturation of those yellow lights as they should rather serve as indirect ligthing instead of being used to light up an area.
I like the "shadowplay" in the second screenshot, maybe make it stand out a bit more?
All in all it's a solid work! Looking forward to get my hands on it.
