RE: how does my form look...
Not bad from this angle. However, I like to have my 'bow arm' straight as a nail. That way I know when I'm at full draw that my arm is always in the same spot. If you allow some bend in the 'bow arm,' I believe that each time you draw your bow, you could potentially be changing your anchor point, affecting the stability, and even reducing the amount of time you could hold at full draw on an animal that needs to take a step or two before you can see vitals.
I think your 'draw arm' looks fine as long as you know where your anchor point is or use a kisser button.
Hope this helps!
