One thing that I notice is that your draw length is probably still a little long. When standing up straight your iris of your eye should line up with the end of your nock, and with your belly button. This should all be one straight vertical line. One good thing is that you are not leaning back, so it is not WAY too long. Len covered some good points for if you are going to be using your bow for hunting primarily, but you do want to straighten up a bit so your bow arm is parallel to the floor and your back elbow and wrist should create a line parallel to the arrow. With the loop your arrow looks good and as Rob said you should relax that bow hand. I had a guy tell me once that you want your bow to be in your hand as though your were holding a baby bird. That is you are containing the bow, but very relaxed and gently.

Apply these things and what the others have said and you should be in good shape. That is if while thinking about everything you've been told you don't develop target panic.[:@]
