Try avoid wearing cushioned sport shoe to squat. It makes you so unstable and shaky during whole squat session. Wear hard sole shoe like converse or just squat barefoot if you can't afford squat shoe. Either improve your ankle mobility or just invest a squat shoe will be better option than squatting on weight plate. I did that before but as weight goes up, you are increasing your chance of injury due to accident.

Depth seems fine and just hit parallel.

But when you lowering your body, make it as a whole movement. Don't separate upper body and lower body. You are lowering your upper body and bend your knees after that. Do both at once and not doing it separately. You only did this correctly during your first and second reps.

For your first reps, always take a big breath and brace your core before you start squatting. Control the weight and don't rush.
