Whereas a "broad" lighting technique will have very little side to side variance in lighting. This will give the impression of a fuller face.
These lighting arrangements are best handled at the time of exposure. Blansky (on this site) would be the guy to talk to on actual lighting set ups. He is a wizard at this type of thing. Anyone that can work with children at his level of competence and still play hockey is to be admired. He is a humble man and you may need to draw him out a bit...he is normally quite shy and retiring.
The model was not of your choosing and so you can't be faulted entirely for what the camera captured.
