My avatar is my Final Fantasy oc from AOL rp rooms of old, an actual sprite from Final Fantasy 1, and kind of a grouchy mascot for me: The Black Magic shopkeeper!
If I didn't have him in my avatar it'd kind of defeat the point of my name.

And my sig is self-explanatory. Shameless advertisement of my webcomic!

So yeah.
I draw my sigs and avs because I can.
