Your upper body should form a "T" at full draw, see the photo by Rack Attack, your right fore arm should be parell to your leftarm Your left arm should have a bend to it.
Your realease hand looks a bit far back also .
like Rack Attack said some shooters do ok with straight arms. I'm lucky because I can shoot with a bent arm and still shoot a 30 inch draw length. I feel alot more comfortable with a bent arm. It keeps clothing and skin away from the string. Good luck Jim
