Celestia and Luna - Harmony

So the other night at around 11pm I had this strong urge to draw, and well, this is what came out XD.
I had the original idea of trying to do a yin yang sort of design with Princess Luna and Princess Celestia from My Little Pony: Friendship is Magic, given the elements of harmony and the day night ruling thing I figured it fit. Originally I wanted to have them making or in the yin yang, but that wasn't panning out very well ^_^;. but anyways, I'm still pretty pleased with my end results (even though the colors aren't very good given we have a dino troll-infested scanner.).
Anywho, I hope you likes it ^_^
