Skt,

Form is everything in archery. Those vids will help a lot, but do it right. Start at the very beginning of your shot sequence, beginning with foot position, hand placement, etc. Work on one part of your form at a time, perfecting it so you don't have to think about it. Then move on to the next thing.

And DO NOT shoot an open grip. That tightens muscles that should be relaxed and often leads to grabbing the bow. Shoot a very relaxed grip.

Notice Randy Ulmer's anchor in the first pic. Doesn't look to me like he's dragging any kisser button back to the corner of the mouth like most novices. DUH!!!!!!!! Get the drawlength right.
