Zak covered most of what I would have said, the most important of which was to never draw your bow without and arrow nocked. Trust me, a hole in the wall is easier to fix than a bow that has exploded from an accidental dry fire.

As has been mentioned, bring your bow arm up a bit and try to bring your release arm down.

One question though, how well do you shoot with your form like this? Consistency is key, if you shoot accurately with this form, don't worry about how proper you look standing there, concentrate on consitently using the same form over and over.
