I don't think her draw looks too short, she just need to change her stance a little and stand more straight. Probably won't make her shoot any better to be honest, but it might be more comfortable in the long run.
Any time you change anything though it takes some getting used to.
I would advise having her tie her hair back, she is going to end up getting it yanked out or something when she shoot with it hanging like that.
My girlfriend shoots as well, but doesn't want to hunt.
And you have a looker there for sure. Wish her good luck this season for me.
