You cut it about 2 inches high, and your knees are coming forward too much for my liking. I'd like to see a side/front view.
It looks like you're plenty strong, you just need some work at a lighter weight to get your technique dialed in.
When I start having trouble w depth, I'll box squat to an 11 1/2 inch box, which is about an inch below parallel for me. For your knees coming forward, cue yourself to sit back more. You want more of a vertical shin.
