I like avatars that don't change much. That's key, no change. Should not be too dark or light and it should have a prominent feature that makes it stick out so it can be recognized. Topless women and "Good", I stress the word "good" Hentai is always a welcome sight. The Furry thing is regrettable which can can be a good thing or a bad thing but people always tend to focus on the oddness, which is understandable.
