Ok, I created a website so I could host pictures again. I will post a few of my girlfriend and I to give you an idea what to look for. Keep in mind neither of us are pro archers and we don't have perfect form. But she is (My girlfriend) a new archer and a female of average size so it might give you an idea of what you are seeing or what to look for.
This is her with her new bow (hoyt rintec) using a back tension release while getting a lesson at a loca pro shop.
Rather than post the rest of the pics I will link to them since some are a bit larger and it would take a while for them to load on the page if I posted them all.
The is the same pic as above, but larger so you can see it better.

And one of her with her old bow (alpine Micro) when she first started shooting.

Ok, now that you have seen some pictures, this is what you should look for.
You want her back, shoulders and head straight above her hips. You want the head and neck straight and level looking forward. She should NOT be tipping her head into the string.
Notice how relaxed we are in the pics, this is a good thing.
Bow arm should be straight, but not locked, a slight bend is ok as well, but not too bent, this will be hard to hold at full draw and will promote torqueing the bow.
Her release arm should have the elbow even with or above the line of the arrow when at full draw. You will see in our pictures we are pretty much even with the arrow, some have the elbow higher than the arrow. This is fine, just don't have it lower than the arrow.
You want her release hand relaxed. Look at my picture and notice how my fingers just lay there when at full draw. You actually want your whole body relaxed. You should be using only enough muscles to hold the bow at full draw and stand upright.
With your head erect and looking forward try to have the string lightly touch the tip of the nose and have it bisect the corner of her mouth. Also pay attention to where the arrow touches her face and where her hand touches her face. These are her anchor points and they should be repeated exactly from shot to shot. where her hand touches her face depends on the type and length of release she uses, and if she uses a loop or not. If her hand is behind her head and she can put her thumb behind her neck either the draw length, the loop or the release is too long. It should be somewhere near her ear or right behind her jaw bone.
If she uses a peep she should be able to draw the bow to her anchor points with her eyes closed then open them and see through the peep. She should not have to bend her head into the string or move it around to find the peep. The peep should be set to HER, not the other way around.
These are just some quick pointers, if you have questions ask.
Good luck,
Paul
