I wish your image would show up without having to open since it would be easier to compare. I added a little to both sides since in your image the hair was so close to the edge. In the original you might have a bit more room. If you framed it you would need to add even more to the sides.
Normally I do not like auto adjust but I use curves or levels, although yours worked okay with auto adjust. Except for the face. I would work a bit more on it since it made them a bit more milky than they should be. Since it is not mine I do not want to do too much to someone else's work. The extra light would have helped. But since this is a nice image you might want to try and "play" around in a program.
