The Chloe Agnew forum has a delightful sketch, made by a fan, of Chloe in an Anime interpretation. While fan sketches usually don't look anything like Chloe, this one I really like! The doll-like eyes are very expressive.
As the original thread suggests, Anime is Japanese in origin, and the fact that Chloe "translates" into this art form so well suggests why she is so popular on the Japanese tours -- at least, based on what I gathered from the Japanese TV hosts' comments (which a few individuals helpfully translated into English) from the YouTube clips.
The thread on the Chloe forum includes a link to the fan's portfolio page.
