Since I consider myself to be a fairly flexible artist I want to several options for icons.

I know an avatar, or icon, is the face of a lot years and can be as unique as the individual running the account. I want to be an able to offer a range of styles. I know I want to offer things like animated transformations once I'm confident with animating. Are there other kinds of animation that I should offer?
What about still icons so I can have a wide price range to accommodate every ones budget? I'm sure ill want to offer couple icons and headshots.
If you have any ideas let me know. :O
