Doug....all looks good but you rear alignment as stated before. You head is right were it needs to be making you a perfect "T" from that angle. Also, you head being in that position is natural and will be easily repeatable on more awkward shots. If you took an over head clip, you would find your drawing elbow at about 5 O'clock and it needs to be closer to 6 to get more bone on bone and back tension.
Looks like you are a good shot 'as is', but where you will run into trouble, again, is in the field when you are muscling the bow and have to contort those muscles from an unorthodox position.
If you can incorporate a double anchor, and groove that in, I think your groups will tighten up more and give you the repeatable consistent back tension.
Of course, when you change anything it will feel weird at 1st, but will become natural and feel normal with repetition.
