Personally I've made a couple tweaks to my form already after

demonstrate the 5 Worst Exercises for Your Shoulder and how
you can turn them from shoulder injury exercises to shoulder

P.S.  Not to be pushy but grab these now.   It looks like they will
only be free for download for another 48-hours.
