Character Creation Has A Race Problem

[PaulCotton]

but if the nose and lips are slim and thin, is it really a black person? No.

You bring up an interesting topic, thank you.

However have you considered that this is a fantasy world where Africa does not exist. These people are:
Elezen.
Hyur.
Lalafell.
Miqo'te.
Roegadyn.
Au Ra.

You are right that a light skinned person with caucasian features can create a close approximation to their own appearance...

The art style here is based on anime tropes and the art of Yoshitaka Amano. African's are not commonly seen in Anime and when they are their drawn representation can appear a bit racist.

If you don't want to look like a little light skinned anime babe then make a Roegadyn or an Au Ra with some wild skin color. Create something that isn't commonly seen if you want to express your personal diversity. Create diversity in the world of Hydaelyn.
