There are two ways I know of that you can shorten your draw, and still draw to an anchor on your face. You can either bend your bow arm elbow more, or stand more open (facing) to the target. Having no experience with this other that shooting my grandchildren's short bows from time to time, I can only recommend that you try both, and see which one you like the best. I seem to be able to shoot more accurately by bending my bow arm more, but Fred Asbell recommends standing more open to the target. Neither one is ideal, but people have learned to shoot accurately with worse accommodations.
