I've compared bloodshot tifa's face with some other artworks and found this
The third and last one from the left, the dissidia one, is more likely to be chosen...
I've also took some measures with the intention to help, not criticize, most measures were pretty similar but others had a small difference.
One difference I found was the eye to eye distance, because the eyes size was increased but it took away some face simetry, leaving the eye to ear distance a little small, or maybe her eyeballs are too much lateral they could be more medial. But this isn't such a big deal.
[I'm not sure what the hell I did at those units but i think they're in inches not meters, sorry I was a little sleepy when I did it]
Generally I think her jaw/ cheeks near the chin area could be a little rounder a little larger (Tifa has sort of a round face after all) and her head is a bit long, I guess that could be fixed rising her nose, mouth and chin a bit.
(I think the head that I took those measures was a little turned to the left, therefore not showing her ear maybe, or not idk).
Still she's already a great model if you wanted to release like that, I definitely wouldn't complain
, I'm just trying to help some way I can :X instead of just saying, oh great model can't wait when she's gonna be ready and things like that...
[I did using zoom, maybe that's why the unit/ measures are so crazy, but the proportion is right.]
