Howdy Jon!
Curious as to what mobility work you are doing for your squats? We rarely find this is necessary outside of stretching the shoulders to get the bar into the correct position.
Both the eye gaze and "chest lifting" here make these more closely resemble a high bar squat. These are super common habits that you're going to have to beat out of yourself.
Look down at the ground 4ft in front of you, think about shoving your belly straight down between your thighs, and drive up from your sacrum instead of lifting your chest.
