First, please read the sticky - we can't help you if we can't see you, and black makes it very, very hard to see landmarks, which is why we ask you not to wear in, in sticky, when filming form checks.
These all apear high, by about an inch. Part of the problem is that you're trying to sit DOWN to depth, when you should be sitting BACK, and bending over more. Get your knees forward sooner, and then sit BACK / DOWN (while bending over) - really reach back. Keep the knees out hard while doing this.
The other issue is your head position - you're pointing it down between your feet. Pick your head up to a more neutral position, and look at a point 5-6' out in front of you. Keep your head still during the rep. Just move your eyes. Finally, show more hip drive out of the bottom - drive your hips up hard.
