I thought of China and Mulan looking at that door as well, Mia.
I looked up a list of animated Disney movies trying to think of other possiblilities for the doors. Here is my list — Agrabar (Aladdin), Neverland (Peter Pan), Atlantis, Mt. Olympus (Hercules), India (Jungle Book), England (Sword in Stone & Robinhood), France (Hunchback of Notre Dame), Kingdom of the Sun (Emporer’s New Groove), Naboombu (Bedknobs & Broomsticks), and Treasure Planet. And then the only land outside Disney I could think of was Oz.
Can anyone think of anything else/kingdom/world, and do any of those doors look familiar for any of those stories?
I think that gray chimney-like thing reflecting in the mirror is Regina 😉
