So for Pinkie I decided to go for a more pattern-like, cotton-candy-ish coloring for her. (And she naturally smells like candy too!) Gave her cute little blue bows for her tail and mane because its heccin cute. And I always thought she would look good with a multi-colored mane, so I had to the opportunity to do so!
Remember, this is my personal take on Pinkie Pie, so you don't have to like it.
