I know there's been a few articles about this, but I actually wanted to write an article about what I think about the movie. As most of my articles say, please do comment and like if you so desire. However, your comments should be written in a way that is constructive and not meant to hurt or insult others. So now I will start :)
So when I first heard about Rainbow Rocks I wasn't very excited about it. I heard the "Shake Your Tail" song and I didn't like it. I also did not understand why they were doing a battle of the bands. However, once I saw the trailer with the villains then I understood...
Trixie's Cutie Mark: This may sound weird, but I think her cutie mark is fascinating and simple at the same time. I love the colors, a light mix of blue.
Sunset Shimmer's Cutie Mark: Her cutie mark represents her very good. The colors go well together, because they are the same colors 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.
