The others have already got the draw length thing covered. The other pic that gets my attention is the one where you're head-on to the camera. I see several things there that could stand some work.
One thing that makes it look like you've got a death grip on the handle is you're holding the handle like you're carrying a suitcase. That makes the inside bend of your elbow point up and brings the meat of the underside of your forearm into the string's path. I hate string rash, and it looks like you do to, the way your head is bent forward and you're holding the bow out away from your body, trying to keep your wrist from getting stung.
Do this, right now.... Hold your arm out, hand straight, fingers extended with your thumb straight up. The inside bend of your elbow will be facing UP.
Now, from your shoulder, rotate your arm so that bend is facing sideways and your hand is flat with the thumb pointing to the RIGHT.
Okay, now, leaving everything from your elbow to your shoulder just like that, rotate yourwrist so that your thumb is pointed upward at a 45 degree angle.
Relax your wrist and hand, letting your fingers and thumb curl naturally. Relax the elbow, keeping it straight but unlocked, with a slight NATURAL bend.That is the exact position you want your arm, wrist, hand and fingers when you're shooting. (I don't at all believe in putting an artificially inducedbend in the elbow! Puts too much strain on the muscles and connective tissues when the bone structure is what should carry the load.)
If you don't want to use a sling, then lightly wrap your index finger around the front of the grip. The other three fingers can be curled up into your palm, between your palm and the bow's handle, if you continue trying to grapple with the grip. You can't grab if those fingers are completely out of the way.

And curling the fingers in will remind you to keep that elbow bend facing sideways.
Once you get your forearm out of the way, you can start holding your head up and bring the bow more in line with your shoulders, rather than holding it away from your body and leaning your head sideways to get clearance. You want your head erect and over your hips so you're well balanced. Right now it looks like you're gonna topple over. Also, you can relax thatbow shoulder and let it ride low when you shoot.
Notice how many times I've used the word 'relax'? To me, you look totally wired and tensed up and the more muscle tension you have in your body the less consistent your accuracy will be. RELAX!
That will be much easier to do once you get everything properly aligned so your bone structure is doing the work.
