Not too bad.
Critique:
* THE GAME BUTTON & POINTER D: Never let them slip into a video.
* Annoying red thingy in the bottom right of the screen.
* At times the camera darted away from the action, I know you were aiming for a fast movement but try & keep the action in view.
* The slowmo parts were jerky as hell, to combat that you need to record sections at double the FPS & apply a tiny bit of motion blur to keep it smooth.
* No music credits, credit where credit's due etc.
As I said, not too bad but with some easily avoidable annoyances. Effects weren't overused, some of the shader changes were a bit glitchy but since it can be difficult to get them 100% fluid & it's not worth picking on for that reason.
Bonus + points for recording in HD, not having crappy borders, keeping the into short etc
