I constantly make Asian sims. I use Pyxis' Huckleberry pie as my skin.

The makeup I use is s-club, it slightly took away their features (sorry) but I like making my sims glam and I still believe they look Asian.

the one above is my fav of all the sims, she looks like she'd be the serious/ mean type in a Korean drama.

This last one was my attempt at making a Filipino sim. She still needs some work (most of them do, but I have them in my bin for future adjustments)
But I only trust Pyxis for Asian skins. As I said before, their Huckleberry pie was used throughout.
