First,don't pull the bow back without an arrow.


Looks like your arm is locked out and you are actually pushing your shoulder forward instead of letting it come back into place(bone to bone).That may explain the shoulder soreness.These things cause tension,you need to relax.


Some other issues I see is your bow hand needs to be turned out.You need to turn your wrist and forearm outward to about a 45 deg angle.

You need to relax the bow arm,turn the wrist and forearm out,allow the shoulder to come back(NOT UP) into the socket.This should help with fatigue and soreness.


Once you do these things,you will see your anchors change on your face.You should be able to lower your release hand which should allow for a more solid acnhor on your face and allow the string to touch your nose and corner of your mouth.
