An image Yoda taught me re: the elbow position/right forearm was to imagine I was going to 'spear a fish' at the ball, or alternately, think of a right handed javelin throw through the ball (to your aiming point). The motion is basically the same, except you want to keep that right wrist bend. Keep that javelin 'in line' with your forearm, and your elbow will take care of itself.

Nice! These are fantastic images and will put your right on the Turn Shoulder Plane as well.
