This mask is for the shots in the dressing room. In the story she is auditioning for the main part in a musical and the scene in the dressing room is her imagination as she sees herself getting the part. It represents her dream of being a successful ballerina; the fact it is a mask as well shows she uses it to hide behind.
Other props I would like to use is a poster of swan lake Russian Ballet or of a famous ballerina. This is to go up in her room and use as a transition shot between her room and the ballet studio. I also plan to have her reading a few magazines to show the influence of media on her.
