The draw length of the bow itself is pretty close. At least no more than 1/2" long. The problem, as mentioned, is your body position. You're leaning back at the waist---because you're stretched out too far. Already mentioned, but it's the release. Way too long as shown by the drawing elbow being below the hand at full draw. Oh, and part of the leaning problem might just be that you have more weight on the rear foot. Try balancing your weight better between the feet.

Some better pictures would show a shot from behind and slightly aboveyou to show forearm alignment with the arrow.
