Wasn't bad...Here what I think it needed though.
-Intro Was a little long.
-When you zoom in, you follow the rider. Be "slower" than the rider.
-Keep the camera stationary with minimal movement for in park shots. Some people get sick of the little jitters. If you want to pan, keep it little and make sure you have a fluid tripod/ cable cam/ helo. Thats if those were available. Additonal panning can be done post production in the editor.
-Add slow motion seens...well variable speeds. Regular on approach->Flash Transition->Slow Motion for trick->Flash Transition->Slower than regular but faster than slow motion.
-Stationary shots. Maybe just point the camera zoomed at the lip and have someone due a trick. For example YouTube - That's It That's All | Best Clip | HQ Remastered
at 0:23. He hits the kicker but the camera doesn't move.
All i can think of at the moment, but it wasn't bad at all.
