There are some unusual aspects to the shot. The shadows on the left face make it look like a strong flash from the left side (notice the nose shadow is photo-right of the nose). On the other girl there is a more gentle lighting, seemingly from above and maybe a bit to the right. Notice the fingers on her shoulder, and in particular the round pearl on her left (photo right) earring. There's virtually no shadow there. It's possible this was natural light and not flash, and they were under separate fairly directional spots, but that seems unlikely.

My first reaction was that a combination of harsh lighting, hair pulled back, heavier makeup and a short lens has seemed to lengthen the girl in red's face; the lighting in particular making the nose look longer.

But there are a lot of portrait processing programs which will change the structure of people's faces - making them longer or changing the shape of nose, lips, etc. Portrait Professional is an example. Many of these, by default, do change facial structure in addition to clearing up skin, cleaning up hair, etc. all by some programmer's definition of "beauty". Women (and probably men though it seems less frequently done there) rarely seem to like their own face changed around, even if other people think it an improvement.

It seems possible that such a program was used on both girls, creating both a distorted view of them (relative to reality) and some changes in lighting.

One other aspect that points to some kind of manipulation is the girl in white's left (photo right) arm - the right side just fades out, yet clearly was well within the DOF of the shot. Could be some ill-applied brushed-in darkening of the background.

I would be just guessing, but I think there is some manipulation of some sort going on, probably a bit too short of lens, and poor lighting.

You could always ask the photographer, or for that matter if they do not like the editing, ask to have it redone.
