You're coming around the ball early. The second (behind-shot) video shows this perfectly - fly-away elbow and slightly high flush finish. You've got to stay behind the ball longer to maximize the ball reaction, prevent deflection, and improve accuracy.
Keep that trail leg down for better leverage and better rotation.
Practice, practice, practice.
