I found the pic of me shooting, with my shoulders hunched
back!

That a CZ 85 I see there? 
Just a quick observation: that "hunched back" stance isn't
really conducive to accuracy and timely follow-up shots as the
rearward center of gravity makes your upper torso unstable and more
susceptible to movement from the gun's recoil.
Regardless of the stance you use, your center of gravity should
ideally be slightly forward of your body's vertical centerline such
that you feel just a tad more weight on the forward foot.
