M3 works as a moviestar mesh because his base look is that bland, characterless "handsomeness" of the Calvin Klein boy toy all grown up and ready to sell insurance

A very colorful statement that is probably dead on! LOL   M3 does have an androgynous look to him that does make him a good start to the Hollywood or model ideal of today.

But then again, I've also seen in FaceGen that the V4 face geometry (not quite as dense as the M3 figure's face) can also make a convincing male character, and I suspect the same would be true with this FaceShop software.  It might be interesting to use her face in conjunction with Vittorio's body morphs to see what comes of it.

Base textures can also be further enhanced with displacement maps to achieve the cragginess ... but there aren't any "make art" type buttons for that kind of work. 8-)
