Jumbojet bhai.
Changin AVATAR is a very serious decision in one's life.
You have to consider various factors.
1) What icon can represent you best
2) How content will you feel with it
3) Who will notice it.
4) What would others perceive of you, as an Avatar is a serious window into someone mind.
Forexample, a flag would show how happy you are with that nation, a certain car would express your love to that machine, a military avatar would show your interest and attachment to certain type of machine, and military machines indicate a serious, aggressive personality.
A cricket bat would indicate a sports minded person, etc.
and a Doll would indicate.................
LoL
Its all good in this neighborhood.
I am just teasing you brother...
