second to all of that above, especially getting decent shoes, of any kind, with a good wide flat sole, i personally like squatting in pretty high oly shoes
also just get tight. in the front shot of the squat you look pretty loose. if i was your coach id have you move your stance in for a while til you can drop down into the hole and stay tight as a drum. ive always found wide stance squats for the raw lifter are great if you use them to harness the power of the glutes and hams by treating your body like a crossbow, loading up the tension slowly and exploding back up, but if you try and drop down into the hole with a wide stance it exposes any mobility or strength imbalances you might have (youre not even that wide but it still seems to me to be the same issue).
id also not focus too much on breaking at the hips first, works in a suit where you have an artificial tension harnessing device, but watching jay nera and a few others squat recently has done wonders for my technique, really upright body position and pulling the hips down between the heels are two of my current self-cues.
