Kazuha's musicality 

I get tired of people saying that "of course she's good since she was trained in ballet" - you could learn ballet for so many years, or take dance classes for how many years but the ability to HEAR music is a separate gift. Especially for the moment like the one shown in this short, you have to have great sense of rhythm. This is a long winded way of basically saying that... Kazuha is extremely talented, and I want her to get noticed for her musicality that is beyond just technical skills in ballet.
