Looks mechanically correct to me, but I have never done them and I'm not the guy to give advice about them. I would predict that anybody able to coach you would want to see a different angle than straight profile.

How about your eyes and where you're looking?
Not bad at all. You started losing some knee extension and using more back/hamstrings as the set went on. Really focus on starting the bar with knee extension. This is very important, but it happens when fatigue starts setting in.
As far as the back extension goes-as you noted-you don't need it. In competition, its much more important(actually, essential) that the knees are locked at the top and the torso is "upright". Just keep the shoulders locked back. Most of us are guilty of hyperextending the lumbar region at lockout at times, just work on minimizing it.
