I would say you're definitely over drawn, by probably 3/4 of an inch by my estimation.

You're leaning back.

Your bow arm is locked.

You have too much palm into your grip.

Your release is too long.

Personally, I'd work on one thing at a time starting with your equipment and then working the new stuff into your new form. Take the bow into the shop and have the module swapped out. If your bow came with a box of modules (most Martin bows do) it should also have come with a module chart. Find the module that is one inch less than what you're using now. You may be able to swap it without a press, but once and awhile you'll find one of those screws right behind the limb and you won't be able to get to it without pressing it.

Next, trade that release in for one with more adjustment. You can adjust it down so that your hand ir further forward on your face and you won't have to reach quite as far with your finger to trigger the realease. You'll be able to learn/apply back tension with a more adjustable release as well.

Once you've got the module swapped out have the shop help adjust your peep to fit you again. Don't try and adjust your head to see through it where its at now, adjust it. You'll save yourself a lot of headache and help prevent poor form habits from getting worse.

With a shorter draw you'll likely be able to work on unlocking that bow arm. A slight bend is all you need, just enough so that you aren't forcing your forearm into the path of the string. Also with a shorter module you should straighten up some as well.

After all that, work on rotating your hand so that you have less palm into the grip.

Start with getting the equipment to fit you and then work on YOU. But... I'm really just a novice at all this, so I'll let someone more experienced/wiser give you better advice. Thats just where and how I would start out.

Good luck!
