Alrighty, I gave it a look.
The backrooms are looking very good, only the entry room feels a bit … sensory overloaded. I have divided the shields a bit to make it better readable and not a mess of yellow and white.
All in all is it ready to go, the only thing I see in the first two rooms is that you start the description in a ‚you‘ perspective, but immediately drop it afterwards. Either dedicate to it, or drop the you altogether and stay objective. A more personal you description is more suited for an action room, with the description acting as a rough mood provider, than a static building.
Exits, area and everything is good, could get linked.
