Awww, poor bird :,(
This was rather abstract. Now normally I would suggest you improve your drawing but the style was such (abstract) that I don't think it needs it if you are to make similar animations.
You don't get high marks for graphics but that means nothing in this case, I can't imagine it being any better with improved graphics.
The music was an interesting choice but I liked it, I think it fit reasonably well.
And finally, the poor bird, I thought it was going to be funnier than it was, it turned out to be sad. I'm actually not quite sure what to think about your animation when it comes what emotion it envokes. The style was humorous but the animation was ultimately sad... I'm actually confused right now, but in a good way.
Anyway, I liked this, I hope you make more :)
