It looks like you will need a different bow in order to shoot properly. It's never too late to change a bow and get used to it as long as you can afford it. 3-4 weeks of practice with good form is better than 6 months of bad form.

If you can't afford a new bow now, you might be able to do a couple of the things already suggested.
1) Lower your left shoulder. That will push the bow out a little bit.
2) Ditch the D-Loop Should give you back 3/4". That thing looks long.
3) Shorten the length of your release or get a different one. It also looks like it may be riding up the back of your hand. You want the pressure to be at your wrist, not up near your knuckles. Can you tighten it up any?


Other things to try to improve your form.
-Move your peep to line up to where you feel comfortable. You shouldn't have to adjust your head or anchor point to your bow. Adjust your bow to fit you.
-Don't grab your release. Looks like you have a death grip on that thing. Relax your hand.
-Straighten your back. Whoever told you your string should contact your chest is just wacky. It will interfere with your clothing.
