As far as I know, there is three Yuuzhan Vong avatars for sale, made by Florian Flow. They are all provided with a full good quality outfit. The problem is they're all male. The alternative is to find some greying skin and wear it, but it will miss the tattoos, which are a part of their identity. I wanted to make a female avatar, there is many different styles of them. I used Nei Rin as base, but the tattoos are different. All the body (the picture only shows the head) is covered by tattoos. I took profit of my investigation to notice the eyes of the Yuuzhan Vong are different, not round like us, but like a lens.
