Well to my eyes your squat looks fine. I think you just need to do more squats and by that I mean develop good neural connections and real ingrain that movement within your CNS. It still looks like a very new movement your body is trying to perform. I would just keep squatting paying attention to form. Maybe focus on descent form pause in the hole make sure your maintaining tightness then focus on the ascent.
I can squat 500 lbs for reps and I still have lower back rounding in the bottom which if we are thinking of the same thing is colloquially referred to as the dreaded butt wink. I do not think it has hindered my performance or led to an injury yet. So I wouldn't worry myself about that. You look like you have long legs especially femurs in relation to your upper body which might make you think your knees are going too far forward but really thats just a normal anatomical reaction to you squating down with weight on your back. I have super short legs and really long torso so thats never been a problem but my buddies who are tall all have that. I wouldn't worry about it.
