There comes a time in a pony artist's life when he or she must depict the period of time wherein Princess Luna (as Nightmare Moon or not) has been banished to the moon for one thousand years and the anger, sadness, and regret that must have come with those times.
But I'm not gonna do that today.
So in the meantime here's Luna chillin' on the moon!
I only now realize that I shoulda given her some nachos. A pony's gotta eat something.
EDIT: Fixed her head. It was some kind of alien head thingie. Weirded me out.
