You have a lot of skills developed. Congratulations!
I don’t want to get into a long post but will list just a few things that you’ll need to work on a bit.
1. Tension in your bow hand. You need to transfer the tension from your bow arm to your back. This is both a physical and mental aspect. When you do this correctly it is called “stepping onto the chair”. Why? Because it takes both mental thought and physical movement to do so. When you get this done, it will look like the string just passes right through your fingers on video.
2. Arched back. In your second round of videos, I can see a large arch in your back. You want to keep your back straighter. How – think constipation. Tighten up the butt muscles a little and pull in the stomach just a touch.
3. Rotate your bow arm elbow just a touch. To me, you’re bow arm looks pretty good except for this little aspect. Usually this is done before raising the bow or while raising the bow, not while you’re at full draw. Your bow side scapula is forward and I can see the bow jump forward. Can you feel a slight stretch under your bow arm when it is in position? If you can, it’s a good thing.
Keep up the good work!
