You're either high bar squatting or high bar squatting with the bar in the low posisiont. Knee travel is excessive for my liking, and your knees are moving forward for the entire descent, which is incorrect (Ref pages 53-55, esp. figure 2-50). You may wish to review this thread.
All of this is typical of folks who have back tweaks or injuries (I've done it, one of the other Staff coaches as well). You have to stop the knee travel about 1/2 to 2/3 of the way down (this varies by anthropometry) - and then keep the knees still as you sit back / bend over. Your head position is a bit high, but at least you're not admiring yourself in the mirror like a lot of others who post here seem to want to. Can't tell you about the bar position from this angle. Finally, bar is way out over your toes. Can you feel that? Keep the bar over your midfoot.
