I liked it, but I think you've got to work on your camera movement...
For example, when the car is sliding one way, you are closely zoomed in on it, and then once the car whips the other direction, you YANK the camera to the opposite direction... you get NO sense of movement of the car, and it is very hard to stay focused on the tires or suspension in slow motion. That is the key to slow motion videos.
If you notice on any slow motion clips, like in F1 for example, they zoom in and focus on a particular area. They aren't moving the camera all around and messing up your focus. Hope you understand.
