Like the Principal's office there are some things I'm going to touch up here but here it is for now!
Probably the background you're going to be seeing the most of throughout your playthrough (depending on the route) there will be multiple versions, with and without the statue, lamps, etc.
The background bar in progress has been updated to accurately reflect how close things are to completion on that front and the music bar will be updated similarly in the coming month, pink slots are backgrounds that are finished (or just need touching up), yellow backgrounds are backgrounds that are currently either sketches or linework
