Part of it is the character representation but part of it is also my own definition of what is white or what is westerner and what isn't.
The live action character for the tibetain was badly casted if the race is important to the story. The romani girl went from a westerner folk with actual hair texture to some with flat hair. But I don't see anything else weird, let alone chocking in this casting.
That's because my own set of reference. I was not even able to tell that the first row was about native american people without reading the comments. That's how little I know about them.
