squat: Don't look up. Keep your knees out hard, through the bottom of the squat. You are a little high. Tighten your abs, your lower back, shove your knees out hard, and bury the reps. (That means, go deep). There might be asymmetry, but I need a straight-on view.
Press: are you trying to do Press 2.0? The one in the third edition book?
Deadlift: I'd like to see more on the "lift your chest" step. It looks like you might be a bit rounded in the lower back. Try to take out that slack. When you put the bar down, send your hips back until the bar clears your knees, then bend you knees and put it down. When you film the deadlift, you need to show your setup, too.
