This is one of my most ambitious sketches yet, and surprisingly, it came pretty easily! I didn't have a plan, really. I started with Twilight, then drew Pinkie Pie, then Applejack, then realized her hat could go on Pinkie Pie's hoof. Then I knew I had to do Fluttershy and Rarity somehow, so I fit them in where it made the most sense to minimize the total space required to fit all 6.
This was basically an exercise in Pony Tetris, now that I think about it. Anyway, for those of you that somehow get notified when I do scraps (or you're lurking in my galleries), then congrats on getting a sneak peak on an upcoming piece of artwork :)
