Right, if you hadn't pointed me towards the blown-out part of her neck, I would not even have seen it so fast, for her eyes are clearly the most attractive part of this photo.
I wonder how much it was cropped out of a larger original?
It is fairly tightly cropped, I say...
And it might have been nicer to have used a wider aperture to blur out hte background more and let even more focus be on Katie.
