Quite a few points which need improving I'm afraid.

You really need to sort the white balance, it was all nicotine stained in colour. Next you need to get in closer, it was hard to see what was happening, you need to vary your shots, virtually the whole video was in long shot which quickly gets quite boring.

Also the transitions were very cheesy. Wipes and such don't really fit this subject.

Sorry but that and the music made the whole thing difficult to watch all the way through.
