Some very quick points for you to work on:
BP - try to set up with a lot more lower back arch.
BSQ - get your knees pushed out to the sides a little more and keep them pushed out. Don't let your knees slide backwards when you're squatting back up; keep them in place and use your quads to drive up.
PCL - you're basically pulling the bar up almost entirely with your arms. You need to keep your arms relaxed and straight, and try to pull the bar up using just your legs and hips. Your arms shouldn't start to bend until you start moving down to receive the bar (and I don't think I saw you dip down to receive the bar, you can work on that too).
OHP - your grip is a little narrow, widen it a little, and at the bottom of your reps, keep your elbows forward instead of letting them shift back.
