You've got skills, practice will make you the next Kye Peterson. Speaking of.. How old are you?
As far as making your spins smoother, it looked like you landed way backseat.. if you landed at all. One thing that helped me when I was learning 3's was to find a place in the scenery and focus on that while I jump. It will keep you from accidentally corking.
Nice job on the knee tuck too, made it look stylin'
