Haha, those two videos were interesting, and yes they do look better after.  but what I concentrate is real human features, not "perfect" humans.  I may not be the greatest but well...

Anyways, I tried my best to place a primitive plane with the golden ratio mask on it (image and trans-map applied, no shadows, no light emitter, ambient set at white), same ratio as the image, zeroed Tina and camera rotation & tran, camera pointing straight to her face.  Placed the mask just before her face as best as I can and rendered.

Thus now I see why her height is 7 & 1/2 of her head size, her chin & jaw might be a little too tall (Long face in "full head & face" not applied).  However, her eyes were lowered some already, and there's no way to lower her eyebrows.  It actually looks to me like if I shrink the "Long Face", the mask might fit better.  But I fear if I do that, people will start saying "too young" again, and I'm trying to shy away from that, as I really want Tina to be an adult character (both face and body).

As for the "mad"  or angled down eyebrows, I don't like those at all, I don't care how many photo models have them, I never liked them, I always like the natural looking eyebrows, not high model stuff.  Down to earth, know what I mean?  Real people.

This is interesting though.  At first I didn't care about this mask thing, but it may teach me some things further so I'll have a play with another character.  I won't change Tina, I've already changed her enough and she looks good as is.  Here's the image...
