Re ethnic variations with the V3 figure, recently I created an African woman, OK she's a sort of fantasy type but I think she looks African which was my aim. Alot of work went into her but I feel the end result was worth it. Shamara is here if you want to see an example:

I'm thinking about creating maybe a Japanese girl in the future (beyond the normal morph of the Japanese dials), maybe the extra morphs from the V3NG girl will help me.
