I think I have dawn Luna once before? Well anyway not enough and not in her season two form, which I am far bigger fan of than her original form.
Anyway everything was drawn, even the stars in her mane and the background; those are not images I got from anywhere, they too were rendered.
Biggest pain was her cutie mark, because it had to be added and manipulated to follow of the curves around her flank, and there is no specific pics how they are supposed to look from behind.
I know people will think it as such, but I didn't intend this as a "plot pic", but however you want to interpret it, I just wanted to have fun with the shading and the stars.
