The angle of the jawline is oblique, not square. Notice the rather small distance between the angle and the ear.
The distance between the bottom of her chin and her mouth is 62% the eye/mouth distance, a Phi ratio.
She has a very short upper lip.
The distance between the top center of her hairline and her eyeline is the same as the distance from her eyes to her mouth. This eye/mouth distance, her "midface," is not long to begin with.
While she does have very slight bossing over her orbits, visible from the previously shown 3/4 shot, the overall shape of the forehead in profile is a curve from eyebrows to hairline. In particular, there's no significant protrusion of the glabella. Though the eyes are hooded, they aren't buried in shadow.

Torv has a wide mandible, giving her a slightly rectangular cant to her face. But the chin is still neatly tapered, with the bottom barely as wide as her nose. And the whole effect is muted by her strong high cheekbones. She still has a small mandible, relatively speaking.
Her hairline is round. Even that bit of recession at the temples is rounded in back, not pointed.
Her nose isn't curved in profile, but head-on it's very thin at the bridge, which opens up the eyes.
And then of course there's no beard, long hair, and great skin.
-------------------------
Torv has predominantly feminine features -- jaw angle, chin tapering, upper lip, hair, and skin are all definitely female. Though slightly androgynous, her forehead and hairline still tilts femme. Her nose is neutral. Only the width of her mandible reads masculine.
We don't actually neurologically process faces in such piecemeal fashion. We see a gestalt, an overall shape, which gets compared to prototypical understandings of faces deep in our brains. Just like hearing a voice -- there are overlapping "bell curves" if you will when it comes to gender and the closer a face or voice is to the peak of one curve or the other, that's what determines how gender is assigned. It isn't a matter of being perfect, and no one feature is "necessary" -- rather, it's having
sufficient features that matters to gestalt processing.
Which is why, I think, FFS is most striking when as many features as possible are addressed. Each one may be slight, but out in the real world everything is taken together.
The only feature that isn't addressed by the current battery of FFS procedures is shortening the midface. See, even a lip lift doesn't change that. Changing the midface takes shortening the upper jaw, which in turn would require adjusting the lower jaw to then appropriately fit. This is called "double jaw surgery," I believe, and it's very intensive, generally only performed to correct severe problems with the alignment of the upper and lower teeth. It isn't, in other words, considered a "cosmetic" procedure, and requires very specialized orthodontic training. But there are women will long faces, and they still get read as female, because most of the other features aren't generally masculine in proportion.
