The stretch band photo. For many, as they start to draw, they tend to use the biceps. This comes from the idea that they must PULL the string back rather than to lever it OPEN. You end up with the hand too far back as seen on your second photo. I've always found it difficult to explain this concept with typed words. It is relatively simple to show in person.
As you draw, the string forearm must move straight in to your face/ head. It doesn't move back away from the target, just straight in. From about 8" out from the body to reference position. The movement of the upper arm and the shoulder is away from the arrow line, not away from the target.
The best reference I can give is the video I did with the rubber band. There, I try to show the movement of the draw using the rotational or angular draw technique.
