A few points...
About the whole thing - it bears very little relevance to the song Snow, so why say it's a music video, why not just call it random imagery or something similar. The other main point I'm going to have to pull you up on is how you cut the song when it's not done. Music videos don't do that, so we're back to the original point of why call it Snow (Hey Oh)?
The animation was good (aside from the guy throwing up, that went on way too long) and you've got a good style. All you really need to do is find a decent script for a song and you're onto a winner.
I'd like to see more of your works, but the one thing about your animation style that I dislike is the thick black lines surrounding your drawings - make them thinner, as it makes the whole animation look smoother and there's a good incentive for you to get towards a featured movie.
