Uhh flea, your avitar is already someone else's personal avitar, infact he was created by a very talented comic artist on deviantart.com
I sure hope you asked for his permission before you used it (unless you ARE him, which i doubt because hes from the US and you are posting in an aus thread).
I dont wanna be a bastard, but I know those guys at deviantart get very anal about copyright infringement.
