This lineart gave me a lot of problems, I'm going back to the drawing board (literally) with anatomy after this.
So, Princess Serenity sits alone in the palace on the moon, gazing at her star locket. Earth is courtesy of Wikipedia, because I suck at drawing continents. I ended up making it a little smaller and adding a lens blur because in hindsight, the Earth probably wouldn't look that close. I ended up pretty happy with the colors, even if I'm still mrrrr about the anatomy.
