Just before starting on this I had been looking at some paintings by J.M.W. Turner, who has created some amazing stormy landscapes and seascapes. It directly inspired what you see here. I had a lot of fun with this, and all I needed was one good brush and a bit of luck.
While painting this, the composition was largely determined by chance. I started with painting a lot of randomly coloured strokes in the direction of the wind. From that I imagined a scene and then let some objects appear from the stormy mess. The result is that besides Luna, there are actually very few well defined objects visible: three trees and what looks like a hillside on the right side of the image.
When choosing a character for the scene, I picked Luna solely because I thought a dark blue pony would look good there.
