How about this. I found an old thread about the bow shoulder and cpnhgningct said it this way, "Take your bow arm pointer finger and hold it close to your chest, shoulder relaxed and elbow completely bent like you're holding a baby.
Now from that "coiled like a snake" position, point straight out to an object parallel with the ground like you are holding the bow out there.
That represents high bow shoulder.
With your arm still fully extended and not moving any other body part, lower your fully extended pointed bow arm and point to the ground 4 feet in front of you then raise it right back up to the parallel to the ground position.
You will notice your bow shoulder is much lower now. That's how your shoulder should feel / be when shooting.
I feel like it is lower in this picture, but I will let you all be the judge.
