Also, you're looking up and craning your neck, and not lifting your chest and achieving and maintaining sufficient spinal extension.
So: Don't drop your hips (Don't move the bar!), look at a spot 10 feet ahead of you on the floor for the entire set, lift your chest rather than your chin, and put the bar down in a straight, vertical path.
