The OH squats take some time to get used to. The obvious statement is that you are clearly WAY off balance. The weight isn't the issue, but you are performing these quickly, and it is pretty obvious that you have never really hit your groove yet. Slow them down and get the feel for where your groove is.

Check my snatch form work. It isn't an OH squat from start to finish, but I think you can see the difference in your form and mine, and maybe that will help you a bit? Note in the hole that I'm squating pretty vertical. Knees forward over the toes, toes angled out, not a ton of forward lean. Aside from some "challenge" in catching a jerk, the OH squat portion is pretty solid. The wider your grip the better your shoulders will rotate.
