I've only bought a few textures, and would never buy anything which only had tattoos. They wouldn't be to my taste in style or placement. The only tattoos I'd put on a rendered character would be authentic ones for that person's era. If I ever did an aborigine, he'd be properly scarified. I'd do the research and I'd do the art. Tribal? Bah! There are some pretty handsome designs, but they aren't from any tribe on this world. Carolly
