Replying to "The Week" Critique

The past week ive been filming at my local skatepark and came up with a little edit. Basically, I want to know how you guys thought it came out and what I should do to improve upon it. Im looking into getting a rokinon 8mm, and at the moment I only have the 18-55mm kit lens. Anyway, im just basically looking for an overall critique on this, thanks! constructive critisism and good advice gets +k!
