I hope you guys will add your own avatars
See mine, I made a larger/different one out of the same two pics you can see it on my profile page (Just click my name). 'Ro's got the Mohawk, actually its a Mohawk, mullet, rat tail sort of style, but I like the way she's drawn.
With the avatars you must be mindful of the size restriction (100x100 - 20kb)
