I'd say you've gotten everything you need regarding pointers.

My 2 cents from the video on deadlift is to focus on activating/ tighten your hamstrings, kinda lika your lifting with your backlegs.
I didn't see clearly, but you seem to go with back first and legs second - that is something your don't want in 1 rm.
It should be a smooth flow, and you will activate muscles you have never felt before if you do it correctly.
Look up and chest up, breath in to be tight before lift and make sure that you never lean backwards at end to risk injury on vertebrae.

Squat looks great! Focus on the breathing before the lift, not during. Core tight, Chest up and look up here as well and stay tight.
Find a nice place for the bar on your traps (never on neck) and elbows back to keep it steady.
