Squat: Hard to tell from this angle, but it seems your stance is a bit narrow - get your heels under your armpits. Because your stance is seemingly narrow, it seems like you're sinking forward into your knees instead of shoving your knees out to get depth. I'd hazard a guess you're pushing a lot of these from your toes (look at your heels on reps 2 & 4 particularly). Your wrists are in extension when you want them to be neutral, find out what's limiting them/keeping them in extension (i.e. shoulder flexibility). Which may be related to anothe issue, you could use more tightness in your upper back. Look at reps 3-5, with 5 being the worst. Even when you're grinding out a rep, you don't want to lose rigidity in your upper back like that. Look You're going too far down on some of these by 1-2", there's good articles on here why you only want parallel.
Deadlifts look pretty decent.
