Heya!
No worries. Thank you for the kind words!
You could create a 'science' room, making use of the desktop computers and steel tables. Along with the anatomical model. Also a 'crafts' room doesn't sound too specific, as you could make crafts in any regular class room. If you're looking for a craft like wood working, then unfortunately I do not have a room for it.
I also do not have specific tiles for a gym, cooking room, cafeteria or music room. Those are good suggestions for future updates however, so thank you!
