Front squats are hard so keep that in mind. For your rack position it looks like the bar in on your shoulders. It needs to behind your shoulders closer to your neck. This will make it easy to balance. As far as the actual squat goes I’d try to sit back less in the bottom. Push your hips back, then sit straight down. Yes your knees are going to travel further forward than in a regular squat, but this is not a regular squat.
