#1 don't draw your bow without an arrow knocked with your release.........you lose major style points for that one.

Your draw length looks to me eyes a touch long, 1/2" to an 1" by your body position,anchor, and the slight bow to your draw arm from elbow torelease.(Leaning and too far back)
You are heeling the grip too much....get your knuckles at a 45 degree angle to the riser and relax your fingers. Let the pressure sit against the meaty part of your thumb not all the way down your palm like you are showing. (All of your fingers in the pic areon the same vertical plane)
If you curl in your fingers you shouldn't be able to touch the riser with your ring and pinky because they will be off the side.

Don't grip the release that tight......relax your both hands, tension starts in your hands and winds up in the rest of the shot sequence.

Also get your back shoulder and elbow up slightly and allow your front one to drop down into a better bone on bone position.

It is hard for me to get a full assessment of what is going on with a single plane photo but that's my best guess..........check out the shooting form thread in the Target archery forum to get a better idea of good form and what it should look like and compare.
