a trick i was shown was to "read the eyes" subject with darker eyes are better for these obvious reasons. looks like two, possibly three light-points. i think its a classic 3-pnt set up with combo of reflectors possibly a few "kickers" on her back to give proportional highlights. imho all continuous lighting (and possibly a diffused overhead flash for general fill)
if the image a mag repro the color info would be off kinda like how given her a more sunbaked appearance. heres a magnification I made of her left eye, i think there may be three distinct light points two areas A & B are pronounced which gives you a clue that it may not be using a diffusion screen on those particular lights at least.
hope this helps...
