Good start. Make sure you keep your head down, and work on getting rid of the pause at the bottom. You've lost hip drive, so work on concentrating on driving your hips up out of the bottom.
Knees, at the bottom, should not moving, so also work on getting them forward early, then keeping them still while you sit back / bend over.
Also, knees out.
Finally, shoot your camera operator, and stuff him. That way he won't move around so much. See the sticky at the top of the forum for more instructions on how to film form checks.
