Ballet in Barbie in the Pink Shoes

I'm looking for someone to give an in-depth write-up on how ballet is depicted in Barbie and the Pink Shoes for the first 13 minutes of the movie. As far as ballet is concerned, you must know "Swan Lake" and "Giselle" and you should also know "The Nutcracker" and "Coppélia". Ideally, you would have actual ballerina experience since the movie involves the characters prepping for actual shows so a first-hand look of ballet is important. For music, you should know Beethoven's 3rd and 7th symphonies. (The reason I ask for these specifically is because these appear in the movie). For your proposal, for the first word, please have in quotations the colour of Barbie's shoes. After that, please give me your ballet experience so that I know you're knowledgable of the subject.
