As omeone pointed out, you are doing power cleans from the hang, which is fine, if that's what you want to do. But, the left from the floor is the most effective for the development of overall power. The hang versions of the olympic-style lifts are a good assistace exercise.
Now, to form.
Your rythym is good but you drive the bar away from you, rather than upwards, close to your torso and I would bet you land on your forefeet instead of flat feet/with you butt stuck out a bit. The elbows should always point towards the ends of the bar when doing any of these lifts. That will help the bar move "up through your shirt" as it goes by, rather than be swung to the front.
If you start doing the Power Clean from the floor, check out youtube or Pendlay's site for some help with starting position and drive.
1. bar over base of big toe/balance on forefeet slightly
2. shoulders vertically over bar at start
3. arms descend to the bar by the outsides of the knees/elbows out
4. back straight and angled/ head relaxed and looking forward
