Welcome to the forum. These are all exceptional shots in a great series. You have found a treasure chest of photo oportunities in this place and came back with some real gems.
I like the room with the vacuum cleaners and find it very eerie, but mostly I am drawn to the blue room with the open doors.
In the future, try to post one photo per thread in the critique form so that we can give you a fair amount of time in expressing our thoughts and critiques . For posting mulitple images as you have here, the Viewfinder forum would be the place to show off these great works. No harm done, we are glad to have you with us.
Looking forward to more of your photos.
