Pat,
First, how is your shooting? I suspect (since you are asking the question) you are not very consistent and tend to hit to the left of where you are looking. Huntnut is correct, you are way too far back on your draw. You are a big and strong guy and you are using your strength in your arms to draw the bow and not the bones and back. I can tell that you are using arm only for your draw because your back in the first picture is flat. If you were using the back muscles, you would see your shoulder blade on the drawing side sticking out from your back and not flat .
Also, too, look at where your string hand is. You are compensating for the glasses by pulling your string hand to the right to clear the glasses which gives you no solid point of reference for your string hand. It is just "floating" out there in space.
I would recommend that you don't pull so far back, bring your string hand to the mouth (suggest your middle finger in the corner of your mouth and hand tight against the bones of your jaw/face) and keep the string in front of your glasses lens. This modification will shorten your draw and tend to make your string arm loose alignment with the arrow, but that can be fixed by opening your shoulders more.
Your bow shoulder is too far forward (towards your chin), hold it much more down and back (towards your back) then rotate that string shoulder back more too at full draw -- all the time keeping your string hand in the corner of your mouth and the string in front of your glasses.
Have you been following all the recent discussions on form? If not read through all the recent stuff and look at some of the videos posted and also refer to Terry's "form clock."
