Not much movement in your draw, which I like.

Too much movement in your finger, which I dislike.

Look at your bow arm, when shot goes off, your forearm clinches like a bear trap...no good. Keep your hand loose and your arm stiff and straight. Hold the sight on the target till you hear the arrow smack. Your overall looks O.K.
Hell, everyone can improve their form, release, follow-through, EVERYONE! no one is perfect, but you can work on some of the things these guys have posted.
