I usually pick stuff from my favorite shows, movies, games, or any form of entertainment. 

I don't remember what my first avatar was on this site, I think it was Sackboy or something. 

Mine kind of goes with my name, but more of a personality thing. I'm the same age as Seth Mcfarlene and his crude humor hits home with me.

I look for something that expresses my feelings of joy and camaraderie.

Well before it was kinda random but now the theme is Supergirl. I choose pics were I think she looks the most adorable and that's my avatar.

Final Fantasy is my favorite RPG series of all time and I love the cactaur.

I custom created my Ratchetario character using my graphic arts program. I love the text warping feature it has. I love Nintendo but have in the last year moved the majority of my game playing over to Sony. Since the two are my favorite, and I love collecting interactive game figures, I decided Ratchetario would be a perfect avy for me.

Well, I have the same one everywhere, and have had for a really long time...

Mine's just me, and I've got a pretty great face, so...

I won't go into the details but my choosing method involves pictures with numbers assigned, a dice, me naked and an erection.

It depends for me. I either make an avi based on what I am playing, what manga I'm currently into, use one of my mascot characters, or if a seasonal event is going on. Since it's October, I'm doing Halloween theme characters.

And they're all drawn as well after the 1st avi I used ; )
