JB,
On the right track but a couple refinements are in order.
First, you are lifting too high to start the draw. Lift bow hand, arrow and string hand only as high as your nose (certainly no higher than the eyes). KEEP THE ARROW LEVEL TO THE GROUND!!! Right now you are "skying it" and lifting way too high. The motion is essentially correct but starting that high, you are engaging your Lats (under your arm and down the SIDE of your ribs) rather than the traps and rhomboids in your back. Think, "around the tree"(spine) and NOT "over the hill" (elbow moving over the shoulder).
Second, Look at your back view video. See how you lower your bow arm to acquire the target? Look at the angle made by your bow arm and spine. It is pretty important to keep that angle at 90 degrees (square). Draw level on the horizon, THEN bend at the waist to set your aim BUT MAINTAIN that 90 Degree angle!!!!
