Man, one good thing about Star Wars and sci-fi, people don't try to inject diversification for the sake of diversification into everything nearly as much. I guess because making the argument that twileks, a fictional race with their own enstablished look, should have asian or african features, or be black or brown, all for inclusivity's sake would be downright silly.
Let fictional races be fictional races with their own established flavours, in other words.
Welp, they didn't have to add African features to twi'leks, because that "established look" you mention was ALREADY African. Yeah, the very first twi'lek character in Star Wars was Oola from Return of the Jedi, and she was played by a Black woman. Good try, though.
Not that it makes any difference, but Bib Fortuna is a twi’lek too!
Oh shit! You're right! I totally thought he was a different species, for some reason. Maybe because of the way his lekku wrap around or something. Well, you got me there.
