If that is Tuyuko, to me she looks like a half breed. Half Japanese, half probably Dutch, since they have a colony over there dating back a hundred years or so...

My image was Tuyuko all right, and yes the genes of the Dutch are everywhere! 

But, this is it for Asian figures that I know of. It only proves your point.

Good luck with your development. Lmckenzie rightly indicated the advantage of keeping a connection to existing supported figures. It was shown with Anastasia recently yuo can go a long way with that. In her case we see also that specific content is provided for the modified figure, not for the basic Alyson2.
