Skate videos are generally shot to focus on the board and the skater's foot movements, not the skater him/herself. To do this, filmers usually hold the camera low. Drop the camera low to the ground and it'll look more authentic.
Additionally, lose the zoom for follow shots like this one. Zoom should generally only be used when the camera is stationary.
And please....for the love of god, don't use high camera shake. Low is fine and adds a little bit of authenticity, but high is too much and headache-inducing.
