Quantity over quality
If quality was rated as quantity, this would be the best thing I've seen on NG. However, I can say that it is definately NOT that. Don't get me wrong, the animation style is great, the music is a little loud in places, causing static feedback, but the parts all seem a little disjointed.
I viewed it and it looks like a group of like minded animators have had one MSN conversation, gone away for three months and come up with a 2 minute animation, which is tenuously linked to the other pieces.
If you spent more time working as a team, you could get a much more refined article. Perhaps rather than using a music background, you could script and voice it. Then even though the animation style changes, the voices could allow you to differentiate the characters etc.
Not bad, just not as good as I expected from an 11Mb file.
