Ooh, your hubby is really handsome.
And yay for mixed sims! I am also part Asian. <3
I think you did a really good job capturing him. Subaxi's skintone was a good choice. (At least that's what it looks like you used, I could be wrong. X__X) If you want to experiment with some other skins, I might try out some of Navetsea's newest ones:
I would try "TSI Edition" or the newest "Cute Edition" because they are designed around Asian features.
