Thinking about it a bit more, I don't think it matters at all if the skin is "yellow or squinty", what's most important is that the shading be appropriate for Asian features (aka, you made a shape with Asian features and does it look good?) Thinking about what skins look best on me, I realized all of them have very soft and subtle nose shading that have no strong shadows on the bridge or near the nostrils. They also have even shading and highlight on the forehead and cheekbones, which suggest a broader face. The lips have to be soft and not enormous or pouty, with no strong shading between the bottom lip and chin. I think that's why Ayumi and Mochi had such success with Tuli's Hope skin, because it's all of those things. If you find one that has a lack of eyefolds or specifically shaded nose bridge it could just be considered a bonus I guess
