Need help finding a movie cause i deleted my access to R/Tipofmytongue - eviltoast

I need help finding a movie about a girl trap in her own drawing. It was a movie that was filmed on HBO or somewhere in 2010s right before or after the movie Paper Town. The movie is about a girl trap in a mostly black and white drawing on her wall and she traveled with a thief of some kind to find a silver mirror to escape.

The end of the movie have a queen that turn into a giant head chasing after her. That is the most memorable part of the movie that i can recall
