A while back I posted the result of an attempt to make my avatar more anime-like, at least in the face. The results were kind of creepy.
Turns out I didn't need to bother. If you want very anime-like and very creepy avatars, go for one of the "Bloom Doll Avatars" inspired by the RL "Blythe dolls" that were initially short-lived, but proved, as the saying goes, big in Japan. Emerald Wynn has the details, with pictures.
