On the down-the-line view, it was my hips moving out toward the ball on the downswing (away from a line drawn from my butt down to my feet).
On the face-on view, it was too much of a slide toward the target on the downswing. (although honestly I am slightly skeptical of this one and need to follow-up on it because this is something I’ve been doing intentionally with iron shots to ensure ball-first contact)
