Excellent
From what I've seen on many of the comments, people failed to read the notes. The animation is superb, you didn't make the music, props go to the musicians, the score is really good, and the constraint of making a story by using a predefined score is certainly a nice experiment.
Your results are great, I loved the ending, I wasn't expecting such ending at the time but inmediately it made sense AND ALSO was in synch with the music, perfect, it really feels like the score was created after the story.
