I would have started with a bit closer shot of the thooth and the toothpast... oh wait, this is the Crest Commercial before your peice...
I especially like the depth of feild on many of the interviews, and I think the interviews cut together well. A good edit pace kept the peice moving. It would have been cool to get the camera in close to the middle of the action.... but then again, that's what most people would expect, so staying out and using the ens gives the story a bit of a different perspective. The last bite seems a bit muddy. Overall a good enjoyable watchable story.
