You are not holding your low back in rigid extension, especially at the bottom of each rep; you should be. Don't look at the mirror; look at your spot on the floor 3-5 feet in front of you for the duration of the set. Don't pause at the bottom. I think your knees are pushing too far forward, but it is hard to see in the this video; lean your torso over immediately as you start your descent.
