/3/ - 3DCG

So i did a few 3D likeness in zbrush before, and everything went fine as fuck. So a new project arrived, and now its Kerrigan time. Easy right? Google images, pint, artstation, youtube, etc. I can see her face well, i can see all the planes, i can see side view, left/right profile view, front view, get ref's from Blizzards cinematics, GG nice...

Well... this monstrosity woman is making everything hard. Im doing everything and still no sign for a good likeness of her. 5 days working straight and not a single good face of her is showing up. Im walking in circles and dont know why.

Im photoshoping my refs, saturating the colors, flipping horizontal, drawing to see new stuff that im not catching at first, but not even these techniquies is helping me out.

Im beginning to think, maybe my refs are all dirty, with perspectives that i cant emulate/do the same inside zbrush?? Maybe what i see in cinematics is not exacly what i see?

TL;DR
Tips to model likeness of a video game character, cuz im doing everything and nothing seens to be working.
