You need to get your shoulders further over the bar, think of pulling in a straight line (up). If you watch the video from the side, your are pulling the bar up and back like this: / instead of this: | (look at your arms at 0:09)
Also, you don't need to exaggerate the lockout, it looks like you're leaning back a little too far at lockout.
