Making Asian Sims

Recently I made my first Japanese sim, Katashi Kito, using my default replacement Ephemera skin (V2)

he looks Japanese sometimes in game but not as often or as much as I would like.

So I googled and found some non-default Asian skins to try - Ephemera WEAK Asia, LFB Asian faces only and SClub Asian skin B for females. There were a couple of others I didn't like so removed them.

I'm not completely satisfied with these and was wondering if anyone had different Asian skins they liked.

Here is Katashi with my default skin, the Eskin WEAK Asia and the LFB Asain faces only

There is not much difference between the 2 Ephemera skins except for a slightly shallower crease on the upper eyelid. The Lady Frontbum one is definitely more Asian looking but I don't like the mouth/lips as much. I guess I could always use a lipstick on him to get less flat looking lips.

Here I changed his hair, brows, facial hair and some of the sliders/shaping of his eyes

Those of you who make Asian sims, what adjustments to the sliders do you make for the head, eyes, nose and mouth?

Any hints on how to make more Asian looking sims would be appreciated.
