Form looks good to me with drawing elbow high, as it should be. Draw length looks perfect, with the seam between arrow and nock being right below the corner of your mouth.

Looks good to me too.

I changed my grip about 3 years ago. I read about the Mathews Staff guys shooting with a closed fist grip with their fingertips on the back of the grip. The only place your hand touches is the "meat" of your thumb and your fingertips. The tips, like fingernails tips, lightly touching the back of the riser but without your fingers touching your bow. .

After a little practice, it is second nature. I'm not sure who to give the credit to, but I read about it somewhere, so it is not my idea. It worked pretty good for me and I need all the help I can get as I age. I simply cannot shoot the way I used to and this "seemed" to make me a little more consistent.

Give it a shot and see what you think.

Looks real good.

There's only a couple things I'd really try to focus on.  I'd use a relaxed grip instead of extending my fingers.  You want a rock solid point where your bow rests in your hand and if you extend your fingers, that point becomes less consistent.  In practice, if your hand is completely relaxed, it's going to be the same for each shot and you wont have to think about what position your hand is in so you can be repetative.  It will already be where it nees to be so you can focus on form.  

Here's an example pic:





The other thing I would work on is getting your weight shifted to where it's 50/50 on each foot.  From your pic, it looks like you are carrying a little more on your back leg than your front.  That often gives the illusion of too long of a draw (some places are really bad about saying everyone is overdrawn) when a simple shift of the hips will bring everything in line.  Picture this, if you were wearing a buttoned shirt, you'd want all of your buttons to be perfectly vertical and perpendicular to the flat level earth and line up with the top button on your pants.  Than line, if extended all the way down to your feet, should be exactly in the middle of your feet.  After all that, you can look and see where your nocking point is in relation to your eye, corner of mouth, etc., and have a real good idea of where your draw length should be.

Looking good and keep us updated!
