I think the pose here works well, a pretty subject with a very natural expression, again your focus is very good, enjoy the complimentary colors (her red hair and the greenish background)
A striking model, and she really does have classic looks. I find the pose slightly awkward - as though this is a crop from a larger more snap-shot like photo.
The DOF is nice, the focus seems really crisp oh her hair though when I'd prefer to see it on her eyes. The crop is way too close I think, it's got that floating head feel. There is nothing really telling about her here, seems like she jst got caught not looking.
I don't know if this was intentional, but her hair appears clearer, or more detailed, than her face/skin -- which works wonderfully, particularly with the title. Great picture.
