Since your trying to improve your distance, here are my suggestions:
Expand your stance- your standing almost straight. You could never get an old busted lawnmower to start with a pull like that

Get your body into a FULL reachback position- azz facing the target, left leg bent with your weight over it, right leg extended back to start your bodys twist, left arm relaxed by your side, and right arm extended far enough to stretch your back.
Pull in, not around- this is hard for most of us to get comfortable with and i think your stance has a lot to do with it; since your not activly using your body your almost forced to arm it. I think i told you about the strech band drill before, imo its a great way to get the feeling but you have to expand your stance to reap the benifits.
Pretend that your trying to elbow someone with all your might.
Grip and looseness- nose up definitely seems to be a problem for you . If you extend your arm out like youre throwing you want to see none of the top, for many throws im looking to see the inside rim.
Examine your grip and get used to cocking your wrist like a handshake.
Stay loose!! Tightening your muscles messes up your timing and leads to arming it.
