Very cool.....
A bit short, but sweet!
Short? Can you imagine how many shots that "short" bit took to make? 
Yes, as an animator myself, I do.

I've done stop motion with actual armature-characters before, and that took a hellava lot of time, and forethought! Not to discredit his work, this is just using lit candles. There's no posing, no fiddling with moving parts, there isn't multiple camera angles...if I were going to do something simple like this I would have made it longer.
