I agree with the fact that the arrow is out of whack. I would guess the nock is simply low. However, every hoyt I have ever owned wanted the nock below level.

In my opinion your head is out of position. It looks to me like you are shoving your head forward to get it to the string. It's hard to see from this angle but I would guess you are also leaning your head forward. Before drawing you want to shove your head backwards ever so slightly. This puts the head above the spinal column, this puts everything in position for proper form and easier back tension.

The effect of this is great.
1. longer draw length
2. It will bring the elbow back and in
- Also makes back tension easier

It would help if you could post pics from other angles. Especially the back
