OK...I agree with SHOOT8S...your elbow is not back far enough. Your head is leaning forward toward the target robbing you of draw length which is partly why your elbow is out of alignment....from what I THINK I saw, your shoulders are pointing too far to the right of the target and should be on the same parallel line as your arrow, this is the other part that is robbing you of draw length and getting your elbow back.
Luckily these are two things you can work on at the same time. Set your shoulders perpendicular to the target, not directly at it, but on the same parallel plane as your arrow. Now when you draw the bow you wont have to THINK about that, but only thing about not leaning your head forward toward the target.
Let me see if I can find the pics to show you...
