The little princesses are utterly adorable, but those faces really rule here. It's not surprising that big sis would occasionally tease Luna, and Celestia even looks so serious about it. Maybe she's jealous because the moon is so much lighter than the sun? Regardless, this is a beautiful picture and a ton of fun. I really love that nighttime lighting made bright by the lovely glow. (It really brings out Celestia's cute meanie face.)
