Good on you for posting up to improve yourself 06. Nothing wrong with that at all.

Greg made a good point about your release being long, I noticed that as well.

Also, and its hard to tell from the angle, but it appears to me that your draw length, as its set on that bow, maybe a hair short. It sort of looks like your elbow is not inline with the arrow. That means you are not fully extended. That long release can make arm position a bit deceiving, and while a string loop and or release really don't change your draw length (in my opinion), they can make your arm position seem as though a short bow will fit right. It looked like the nock of the arrow, when you were at anchor, was right at, or even just a bit forward, of the corner of your mouth.

As a few other folks said, take your time, and watch the arrow hit the green dot (if you are shooting at 20, and your 20 pin is green that is).

As bees knees wrote, if you are closing your left hand, that also means you are punching your release. What the right hand does, the left hand wants to do also. Thats why its tricky to pat your head and rub your belly.

If you keep your bow shoulder (Left) low, and turn your hand 45 degrees to your bow... you won't have to worry about string slap. It will look as though your arm is bent... but it will really be straight.
