The animation is great, the song needs some help though. It doesn't really have any direction, there is no resolution to the main conflict (her nervousness to tell the guy her feelings). Think of "Teenage Dirtbag" by Wheatus - not one of my favourites, but it certainly does a great job of what I'm describing. At first, he feels he's gonna be alone forever, nobody cares, and he's always gonna be picked on - but by the end, the girl he's been interested in finally notices him and comes to him, and offers to go to a concert with him where his favourite band is playing. Super realistic story? No, but it at least goes somewhere and there's a payoff. This one is just repetitive and goes nowhere. So, great animation, but work on the songwriting.
