Parts of this were absolutely amazing, and other parts were just plain awkward. It looks like you could have done SO much more with this, and you just gave up or something. The long spaces of silence when there is nothing to look at, the lack of images of the destruction. On the positive not the beginning was absolutely flawless. There was also an odd sound clip part where the wind was blowing, and then it sounded like you put another clip of wind blowing on top of the existing one and it just sounded sloppy.
Overall I'd say it's a decent piece of work, just thrown together kinda sloppy and not edited very well. The drawings were amazing though.
