I like to see the experimentation with goals and application. As a video, that makes it very interesting.
I would recommend a little more control over your lines ('smoothness', there are places where you seem to correct an angle or position, namely 0:28 and 1:17) that shows that you're using power way more than necessary for the particular corners. That, and there are quite a few apexes you could have hit better.
The tandems were the best part.
Don't get me wrong though, its still 100x better than almost all the other videos here.
