Talk about a remodel! This is a very inspired build and an excellent concept. Converting the old train station is something I'd have never even considered. The lighting arrangements honestly floored me, they create a provocative mood, especially the neon lights against the rusty, corrugated metal in the bubble room.
Two things strike me as places for improvement. Citing the second story deck, I'm noticing that the deck in the top of the photo has a greater width then that of the other side, creating a larger amount of unoccupied space. I'd suggest may dropping a loveseat or even just a plant near the stairwell on that side just to produce some functionality or visual interest.
The bright red rings of the fire pole are a little clashing with the surrounding. I'd consider three options for incorporating them into the color scheme: texturing them as a neutral toned metal or wood; texturing them an orange metal, plastic, or pattern, two mesh with the middle "orange zone" of the dancefloor/the tiger carpets upstairs; or painting one green and the other pink to mesh with their adjacent color zones.
And not really a critique but some personal encouragement. I've been really "pro-interesting restrooms" lately, so I'm wondering what you could do with the bathrooms. Definitely decreasing the number of lights and placing them on polar sides of the room. The little dips in light intensity will increase the complexity of the bathroom without actually really doing anything with it. But try making little details to create an overall unique image. Maybe add a decoration or couch in the empty space.
Aside from that, its spiff. Spiiiiiff.
