I would look for stress marks on the curve of the limbs, mostly on the outside edge, also check the end of the limbs where the cams connect to the limbs, check where the limbs connect to the riser, and this one is gonna sound stupid but check around the grip too. I don't think you did any damage, you really diddn't have it drawn back far enough, but check it out just to be safe. I sure it will be fine.
