Okay. I pulled up a bunch of refrence pictures that I use.
first is a bunch of tutorials that are from here
they have more on the tutorial but these are the points i use. really good. check out their otehr stuff.
I also use Disney concept art for both Moana and mulan.
this artist makes really good mulan sketches and art that I also use for refrence.
this artist I also use as refrence for Asian characters.
Just. definetly look to how Asian or asian-american artists draw asians. This avoids following racist design stereotypes that can show up from now asian artist who don't know any better.
also look at actual asian people. i follow the following two blogs for fashion refrence, but the models are majority asian. and tokyo fashion has a diverse array of people living in tokyo
