[Repost x3] Character gets thrown into the background when her siblings become famous.

Here is a fun one. I did not really like this movie but It is apparently a good one. 2 plots pinned in my profile unsolved. Guesses were Encanto, Blades of Glory and The Brady Bunch Movie.

Hint 1: The main character is an amazing sister and artist

Hint 2: When her parents forgot about her, she destroyed all her amazing art.
