It's a really tough competitive world with actresses and I think Jasmine is the only one with the desire, confidence, ability and beauty to handle that world. I think Ariel has all but the desire.

I think she has the class, dignity, composure to keep up the appearances in public and well she's been acting only half her life. Her personality also has that aura of being mysterious

I maybe biased because Mulan IS an actress in my Modern AU Mulan headcanon( I mean attends theatre academy).
