I had trouble deciding what pose to do for Pinkie, since she's the most random and all over the place character. The hopping is the most common and probably expresses her hyper nature.

Pinkie Pie was more of a challenge with her face as well, but I think I got it down :3 Though, the limits to my colored pencils kept me from using proper pinkie body color. Oh well.
