Hi TopazMermaidWater,
Your avatar looks good! Perhaps you have already changed it.
This is how to change your picture:
Right click on the picture to go to your account.
Click on the middle tab 'edit'.
Scroll down to the picture and then follow the instructions to create your character.
Don't forget to save! You may not see your new picture immediately. It sometimes takes up to one week to appear.
I hope that helps.

Best wishes,
MissInternetEarth
