avatar pictures

For the 18 given pictures, I propose three discriminating categories: Human Imitating, Reality Based, and Non-Reality Based. These categories touch on all the possibilities of these divers avatars; for example the playboy avatar would most deffinatley fall into human imitating, the fish would fall into reality based, and the predator would be non-reality based. These series of categories provide a number of ways to group and narrow down many pictures.
