There are lots of countries that Disney never really brought representation to, recently I have been working on my own not only princesses, but superheroes and etc. I decided a while ago not to make them Disney because I realize that Disney doesn't seem as diverse as I thought they were.
I mean, come on. You can have two German princesses and three french, why do they got to say, "China is already token for Mulan." They can have another Chinese heroine, but make her a princess , and the plot can be completely different compared to Mulan 's film.
And also, we don't even have a Japanese princess, not even a Mexican one, really? Elena isn't part of the lineup, why did they have to debut her in a movie in the first place. There is a lot that Disney has not done and we would still need those countries to be represented: Romania, Malaysia, Indonesia, Japan, Russia, Estonia Finland, South Korea, The Philippines, South Africa, Egypt, Latvia, Lithuania, Poland, Spain, etc.
