A for effort, and I think that a lot of effort was put into the mixing of songs, and it worked. However, what you've come up with is 100% emo, no matter how much you claim it is not.
Nonetheless, the animation was done well. Not great, but well. Some of the segments were better then others, but I understand what you were trying to get at.
It was just relentlessly maudlin. Not mature, just maudlin.
