Excellent video. Only one little thing could you, when you make your next one, add a few seconds at the end where they don't grow. It leaves a little time to admire the end result. I don't know if I'm the only one, but I tend to play these short clips at continious loop.
I used to make the same "mistake", when I made expansion videos and found them much more satisfing with the added seconds.
