Here is my model list organized into want vs. need:
Need:
Room base (floors, walls, and roof)
Desks
Bed (blankets and pillows are wants)
Couch
Drawer
Want:
Shelves
Chairs
Ceiling Lights (Long ones)
Doors (1 normal door, 2 sliding closet doors)
Miscellaneous stuff on desks and shelves (Like my computer and binders maybe)
Clutter on the desks will be a main thing that will bring the scene to life. Also, I don’t know if the ceiling will be seen in the final render, so details can be lost there.
