I don't even know there's a non-animated Mulan movie. But this sounds too "Oriental" (new age though) & too tragic to me; Even Zijun does not use any traditional Chinese music for her program. The Disney movie may not be a good reflection of the true story, but the music is better for Yulia's childish innocence appeal.
from 0:27 the music is not so oriental anymore
I agree that Yulia's performances does not have the depht yet like e.g. Suzuki's, but I think the tragic music + the faster fighting parts would hide her lack of interpretation very well. I imagine it to have a similar effect as her Schindlers list - tragic music and although some of her movements were a bit rushed and juniorish, with the right package most people got the message.
On top of that the mulan theme - simplyfied = girls can be as couragious and smart even in medival times as boys also has a slight political message, though maybe not as strong as the schindler's list programm did.
As you can see, I'm totally for her skating to mulan


unless she pulls the NHK-Hanyu move
