Is your back still bothering you? hurting?
You look way tentative in both lifts, like you're expecting it to snap.
the squat, isn't deep enough, missing by 3 ~ 4 inches,
and we can't see you feet, which me thinks are too narrow,
heels should be shoulder width,
toes should be out, you're aiming for 30*, both sides,
knees track over your toes,
a wider stance should help make depth easier to get to,
lighten up the bar some till you find depth.
