I mentor at our youth archery league and a couple pointers to possibly consider that will help in the long run.
1. get her to shoot withe her arm fully outstretched. Bent arms leave room for variance in your draw while a locked elbow really doesn;t change much. If she has trouble hitting her arm, possibly tuck the two bottom fingers into the palm behind the grip.
2. shoot with a flat wrist so the pressure from your bow is against the bone in the bottom of the palm of your hand. bow to bone contact once again is more consistant than a flexed forward wrist.
3. relax the grip on the bow, if the rest of the form is correct it will settle into a solid bone on bone connection all the way thru your arm back to the shoulder.
4. Try keeping the elbow of the draw hand more parrallel with the ground, it makes it easier to bend your waist instead of your arm to move the bow up on target that way
5. the draw length deffinately needs to be lengthened and likely guessing longer arrows. I teach kids when shooting a release to use their thumb stuck out onto the back of their neck as an additional anchor point. If you have a point on your face the release hits plus a thumb point on the back of your neck, there is a good consistancy in your form which good shooting is all about. Add a kisser button to the corner of your mouth and a three point anchor is pretty consistant.
hope you don't mind the pointers, teaching archery is very fun and rewarding when you watch how kids (not that your fiancee is a kid) progress. A lot of the kids we started out are now taking some really nice bucks with their bows. Good luck this fall.
