Hi, William -- What do you think of this picture yourself?
I'd just say it looks like the focus is off and that things at about the same distance from the camera as her right knee are more nearly in the plane of focus than closer parts. Could it be operator error, or perhaps the camera's RF is out of calibration?
And on the scan, I downloaded a copy of the pic, and I see in the histogram that the data is biased toward the lighter tones (as can also be seen in the post), and some of the lightest tones are "clipped"; that is, off the scale. The darkest tones are not black, but dark grey. Given this, I'd suggest the scanning exposure could be reduced a bit to push the data down toward the dark end a little. Your job wasn't too far off, though!
Then, in post-scan work, you might optimize the tones by bringing the end sliders of the histogram to the top and bottom points of the scan to ensure the darkest tone is black and the lightest tone is white... This compression adds a little contrast and brings up some sparkle to the result. Here's an example of what I'd do...
