Anthony,
You move fast! Just checked out your vid on YouTube and made comments on which points you lost lumbar control and began to move into flexion. Those points are where you become quite vulnerable to lumbar disc injury. That will ruin your day! Others here can comment on other items such as when your knees translate forward too much. Overall, pretty darn good for a new squatter! Keep up the good work and make your form impeccable.
