OK, a little more.
First, look at the videos of your back (both shirt and shirtless). As you start to lift the bow, look at your string shoulder. See how high it lifts? If you draw a line across both shoulders that line angles down at around 30 to 40 degrees. Ideally, that line should be horizontal (flat to the world). That is forcing the muscles across the top of your back and the base of the neck to take all the strain. We really want the "strain" to be much lower in the back -- down around the bottom tip of the shoulder blade.
Watch your self in a mirror and start with the shoulders level, and try to keep them there. It is common for folks lifting something to lift the shoulder but in this case the lift should be with the arm -- just like the bow side.
Now watch either or both of the videos from the front. I mentioned the exaggerated string wrist bend. That is a hard one for many to understand and as I said, it is a little over done, but better than most trying this technique.
Watch as you start the draw. See how you maintain that wrist position during the very first part of the draw? That is GOOD!! Then you start to flatten that wrist and watch the string elbow. It now actually reverses direction. It stops moving to the right in the picture and moves to the left. The flattening of the string wrist causes and allows the biceps to take over the draw and reverses the movement direction.
Keep your wrist out, keep the biceps relaxed and rotate the upper arm/elbow continuously around the spine/torso. For me, it feels like I am leaning harder and harder against a wall on the string shoulder side.
SOOO, Shoulders level, wrist bent (just maybe not so much) and think "rotate the elbow AROUND the spine in a continuous movement.
Kabo, you are really doing well (much better than this may sound) and are very close to a good rotational draw.
Let me know if this helps or if you have more questions.
