It's significantly better but can be improved (see my other post).
See the deadlift chapter. Simply stand up, dragging the bar up your legs the entire time.2) My eccentric phase is painfully long because I'm not a hundred percent sure how to execute it
Regarding the squat, I agree with the other comments. Post a video where you've narrowed your stance a bit, put the bar further down your back in the proper low bar position, and leaned over more fully during the rep. Put something on the floor 5' away and stare at it the entire time. You have bad knee slide but let's see what happens with these first adjustments.
