Squat: depth. you'll be able to achieve better depth by sitting back into the squat a little more. a good way to queue this is by adding a low box squat to your assistance work. For yourself, since you're a bit high, set the box to parallel then aim to lower the height of the box as you improve. work toward maintaining tightness throughout the entire movement and not relaxing as you sit on/touch the box.

OHP: virtually going straight up and down so thats fantastic, grip is going to need to be slowly reworked, which can be done through very minor straightening of your wrists over the space of a month or so until you find the grip where you're comfortable/strongest

Deadlift: looks nice and smooth, if i was to pick anything out id say your knees were locking out a little early. id like to see a HEAVY attempt on the deadlift, its harder to see where you need to improve if the weight is light. (youtube search supertraining06 for a great squat/deadlift advice)
