Since celestia is the older one, she probably tortured luna by taking something of hers. Well, I think that luna would do that right back to her. Celestia was eating an ice cream and luna took it, making celestia wine and cry.
I messed up on celestias eyes, making them way to small compared to her head. Luna's hair looks ok, but I will definitely improve on this piece with an updated version.
