Clearly a keeper.
The subject really engages the viewer.
Compo nice (altho if there is a little more frame on her right, that would be better)
Sharpness is looks right on. Hair detail and background is terrific.
It needs a little touchup for the small magenta color cast, lighten up eyes a little and a little work on the shirt to tone it down.
Some work on the full-res original and this will be a treasure.
(as a personal bias I would crop this to fit in 8 x 10 [crop to 7.75 x 9.75 and add a .25 inch frame] to remove some of the shirt)
