Does the string contact your face at full draw. If you're not tucked in tight it will throw your angle of sight off to the side. I shoot fingers though and don't have any experience with releases. I find my best form comes when the string touches the tip of my nose. Like others have said, your grip has alot to do with it too. Is your arm locked? Open your palm on the grip, lock your elbow and rotate your arm so that the inside of your elbow is plumb. If the inside of your elbow tilts in toward the bow, bad things can happen.
