painkiller, maybe, you could add some more colored lights: red and green for entrances, and bluish for the screens, more yellow for the wall lights... at the moment its veery grey. A tip for more level ideas: broken walls which lead in very different areas, dead end rails, storage rooms with 'towers' of old machines, boards that connect them ... ...stairs, even a few steps make a difference, windows, bars where you can look in further rooms and floors or yards with some sunlight...
