Hey Jason,
You're setting the bar a little too high on your back. You want it just below the spine of the scapulae (bony ridge on your shoulder blade). You also want to get your thumbs up on top of the bar, keep your wrists neutral, and squeeze your elbows down and in towards each other as much as possible. Tuck your chin a little and stare a fix spot on the floor a few feet in front of you toes. Take a bigger breath at the top and puff your chest out really big, and clamp down hard with your abs. As you initiate the squat, shove your knees out wide and hips back, and point your sternum down at the floor. Make those corrections and keep adding weight, solid work!
