Where's Your Crown, Cay Cay?

My first submission! I hope you all like it! If the ship Dislestia is not for you, just imagine them as frienemies and enjoy! 

I am not a master of shading yet and I've not even sketched them like this before now! XD Haha, I love that Discord finds it a hoot to call Celestia "Cat Cay"...What does it even mean? Why does he call her that?!?! I heard on tumblr that it means "beloved"...But c'mon! There must be story behind it... ;-; Awaiting Discord and Princess episode now and forever.  ALSO HE OFFICIALLY LOVES HER MANE! He stole it in the s4 premier and now he's petting it. :3 I cant get over how perfectly stupid that is.
