I agree with Matt on the draw length. Looks like you're leaning your head back slightly and your upper body doesn't look square over your hips.

I'm gonna beat up your bow arm. Starting at the bow hand and working back.

Looks like you've got your hand too far into the grip. The lifeline in your palm should always be slightly outboard of the center of the grip.

Wrist position is okay but there is a rotation problem I'll tell you how to correct in a bit.

Elbow: The inside bend of your elbow should be vertical to the ground.

If your elbow is relaxed and not locked out, with it's natural bend that's bent enough. A lot of people got used to seeing exaggerated elbow bend a few years ago when they were making bows with ultra low brace heights. Had to bend your arm a bunch to get the wrist out of the string's way with those nasty things.

Shoulder: Should be relaxed and held low. Yours looks tense and is obviously high. You wind up trying to hold the bow in position by muscle power, instead of solid bone-to-bone contact.

The way I like to describe good bow arm position:

Hold your arm straight out to the side, palm flat, fingers straight and your thumb pointing straight out to the side.

Keeping the arm straight to the side, relax your shoulder and allow it to drop straight down to where it stops by itself.

From the shoulder, rotate your upper arm so that the inside bend of your elbow is vertical.

At the wrist, rotate the hand so that your thumb is pointing up at a 45 degree angle.

Relax the elbow and allow it to take a natural bend.

Relax your hand and let your fingers and thumb assume their natural curl.

And there it is.

It might take some getting used to at first but, when you get accustomed to it, you'll shoot a lot better with less fatigue.
