Somewhere, I've seen a list of things to do/not do with hands and limbs in portraits. In this case, her hande(s) are problematic, AuntiPode's crop resolves that.
Open your lens to add DOF by blurring background. I've read that a setting of f5.6 generally gives a plane of focus from the nose to ears for portraits. Given the work of the one offering that advice, I am confident he is correct.
Otherwise, being uber-picky, offer her an opportunity to brush or otherwise arrange her hair. And the background is distracting.
Reworked to add some of the preceding and do some clean-up. If you object I will remove it. Perhaps a bit hot for your taste.
