Squat: You are not hitting depth. I think it is due to a too narrow stance. Move your heels out, to just under your shoulders. Turn your toes in some, you have exaggerated the toes out cue (yours look 45 degrees, not the recommended 30 degrees). Lean your torso over immediately as you start your descent.
Press: Get your wrists straight (about 10 degrees bend is OK), yours are quite bent for most of your set. Don't push your head forward and down as you are driving the bar up. Shrug hard at the top of each rep, like you are trying to drive the bar through the ceiling.
DL: Go read the sticky at the top of this sub where I posted a link to Rip's 5 steps for the DL. You are pushing the bar around with your shins during your setup, which is putting the bar too far in front of your midfoot and causing you to drop your hips for that first rep. Stop looking in the mirror. Squeeze your chest up harder (see step 4).
