Trixie's Cutie Mark: This may sound weird, but I think her cutie mark is fascinating and simple at the same time. I Amore the colors, a light mix of blue.
Sunset Shimmer's Cutie Mark: Her cutie mark represents her very good. The colori go well together, because they are the same colori as her mane, too. The suns' rays are wavy, just like Celestia's.
Zecora's Cutie Mark: Zecora's cutie mark is well detailed. The swirl represents the her personality well, and it looks as if a mark that a zebra would have. It looks like it represents her oddness and her reasonableness.
