@beardalaxy i am a fan of glasses (and an user) and i think they made her look more cute....
BUT also the glasses helped fix one thing, that for some reason it seems to me that the space between the eyes seems too big (despite being the same as in the anime), and the glasses seemed to help mask this.
Maybe it's because of the camera settings or IDK, but it happens.
@hideki as someone who isn't a 3d modeller i think I like the 2nd or 3rd one the most just because it the hair shading (+ I'm not a huge fan of glasses lol) but I can definitely tell the look you were going for and you refined it pretty well
