The Shimmering Hero of Canterlot High Poster

Thanks to fiischer for the base. This is a poster that shows what the poster for my upcoming Equestria Girls sequel fanfiction would look like if it were made into a movie.
The movie is rated PG for fantasy violence and some language.
The length of the movie is 75 minutes.
PLOT (SPOILER ALERT FOR EQUESTRIA GIRLS!)
Sunset Shimmer is still upset about not understanding what true friendship was. One day, the Twilight Sparkle from the city gives her a magical compact mirror that gives her magical powers which help her not only solve everyday problems and fight evil around Canterlot High, but the mirror helps Sunset find a foster family in the human world. Little does she know a revived version of her demon self (The spirt of this form split from her body after she was purified with Twilight's crown) along with evil versions of her new friends, planned to rule Canterlot High. Can Sunset Shimmer save Canterlot High and start a great friendship- with Pinkie Pie, Fluttershy, Rainbow Dash, Applejack, Rarity, and Twilight Sparkle?
