can you show her face without the eye cover?
The eyes are one of the most important details of 2B if you ask me, so i took quite some time to get them right (in my opinion)
texture-wise, if you want to stick to the original, this is literally all you have available to make eye textures:
it's basically just a really small resolution blue pixel mush, but you can see that there is some blue-ish glow in the pupil, not just on the iris. When you further research that topic, you will come to the conclusion that the only thing that really sets the androids visibly apart from humans are the eyes, because they are meant to be a window to the soul and instead of a black pupil, the androids have some kind of lense-ish reflection that makes the eyes instantly less human looking.
in the game's cutscenes they used higher resolution models and textures where you can actually see, that it isn't just a blue blurry pixel mush but there are some light blue patterns visible on the irises and also if you look closely there are indicated eyebrow hair textures which just isn't there in the ingame textures:
also, the color of the original texture doesn't translate 1:1 to vam because with the game engine and lighting they always look darker compared to NieR ingame footage so i also adjusted that and came up with my own version, together with the really heavy eyeshadow that she has in NieR Automata and really downward sloped eyelashes and most importantly, the lense-ish looking pupil. Since the game doesn't let you change the pupil texture, I made an overlay as a clothing item to create a workaround to be able to texture the pupil properly
and to further play with that specific aspect of the character design, where the eyes give away their android nature (maybe also a hidden reason why the androids are ordered to cover their eyes at all times? ) , i thought i'd double down on this, so when you really zoom in, you can see that her iris is not just a human iris, but actually a circular circuit board pattern. Not too much to be completely obvious but still visible when you specifically look at it
With the face texture i tried my best to stick to the original feats and colors as close as i can while still remastering her face to some more realistic looking 4k textures
