This is based on artwork I commissioned years ago of my original character, Princess Aerie Evergreen. You can pick up sequins to decorate her skirt from me by clicking here.
 
She's done by an unknown artist from back when I was on Gaia Online. I ordered and paid for the art with the game currency back then, Gaia Gold. This artist was known as "Siran Lucine". There is a DeviantArt profile for this name but it hasn't been active since 2010 so I just don't know for sure.
