Not bad homie, your movements were pretty smooth.
However, I found that in all but the last shot the movements didn't complement the shot - ie they didn't add anything special to it and maybe took away from it because of the way they interacted with the subject. For instance, I've never liked when the dolly moves away from the subject mid-trick, like in the first shot - it takes away emphasis. Also in another one of those shots, you had the dolly going one way and the subject going the other way - thats a bit too much movement for me, and you ended up cutting off his entry/exit. Move with him next time.
That last shot was banger, though. Just keep practicing with it, movement can take your shots over the top. Just be careful not to overdo it though, not all your shots need the dolly.
