You should practice your cam work, a lot of of the time camera wasn't well concentrated on what it should have been and the movement of it wasn't that 'smooth' either, and was too far away a lot of the time.
The back and forth effect was ugly, if you did it maybe just a couple of time it would have been neat, but repeating it over and over again didn't work. I didn't really like the blurring neither.
You should also choose shaders that fit the tori.
Keep on working your videos though, you'll be really good one day.
