UPDATE:
I added the moon to be NMM's eye and I made season 2 luna a bit more distinguishable and I fixed the sky a bit.

I wanted to start selling wallscrolls, and I came up with this :3

This took a bunch of hours to do because I wasnt sure how to make the images in the sky work out. And clouds were difficult to XD

So, if I executed it correctly, you have Season 1 luna on the bottom, season 2 luna in the middle, and nightmare moon on top :3

I image this happening shortly after Luna's banishment.
