I have mentioned before that I dislike Celestias hair before, I decided to give it a chance,
but with my own twist!

I still think that her hair should be more fire like, or sunset-y, but i decided that Canon Celestias hair is a result of Lunas Banishment, where some her power was transferred to Celestia to let her be able to raise the moon and do most of Lunas duties. As a result of This, Celestias hair(which i headcanon that alicorns appearence is tied to their magic and essence) changes to reflect her control of Lunas abilities. Luna has control over the moon, dreams and the tides amoung some things, so her hair flows more like water in Canon than like clouds as in my HeadCanon. I also changed her regalia a bit to show both moon and sun.

So ya, thats my take on the matter, and i think it turned out pretty nice!

EDIT: I JUST REALIZED HOW FUCKIN TINY HER WINGS ARE WHAT THE F U C K
