I think my only comment about seeming to apply the same style to most of the subjects is that she's missing the proper contouring.
Check out everyone with a long face, in many of them, their face looks even longer in the "after" shot. Which would mean she's obviously not utilizing proper contour techniques but a blanket technique which may work on the majority of clients, but I've never seen anyone try to make a long face look longer. As a well-established mua, I would expect more from her.
But, of course, it's just my two cents and my perception could certainly be off from others.
