Strange.
It took a very strange direction with animation, art, and story. Yes, it used an anime style, with far too many anime expressions, but the fact that it was all drawn onto photographs didn't feel lazy so much as it fit the life the girls were leading. The fact that they all had white hair was cool. I saw some great moments in the animation, with fluidity; This is particularly noticeable when she's conducting. As for story, yes, it was confusing, but I was able to understand that the girls had an affinity for art but no real exposure to it before I even read your Author Comment on the story. I grew to like the peculiarity of the storytelling. I disliked that the girls were bullies, though. Those poor kids on the flagpole.
The music was fantastic.
Overall, great job.
