These are all varying degrees of high. Looks like you need to turn your toes out, and get your knees out over them once you do. That should help with your depth. Watch rep 3 very closely and compare it to the others - see how you lift your chest? That's what makes the next two reps hard. Stay with your hips, always. Watch rep 5 - good hip drive, and you finish a hard rep. Finally, fix your head - it's down to far - pick a spot farther out to gaze at in order to have a more neutral neck. You may need to move the rack away from the wall a bit to do this.
