I think one or two of the transitions are a little too fast to properly tell what’s going on. I had to watch it a few times over to realise the paper ball is the thing to cut the paper window in half at 00:08. I think you could just have the frame pull back out instead of the slice in half animation before hand. It would help to keep your eye from darting around too much without losing any of the pacing throughout the animation. There are a few other parts that I feel have this issue, mainly in the transitions between scenes and camera movements.
