You got this pic of a face planted onto a head shape, and that head shape becomes super important for how that face appears at different angles. It looks pretty good mostly from the front but starts to fall apart at this 3/4s view.
I've seen this anime face guid refer to "mask face" there's a dip on the outside corner of your eyes the 'zygomatic' bone. If that part doesn't tick in, as the head turns it makes the face less believable.
You want to hyper restrict your polycount I see but this detail is really important. Youll see other low poly models sacrifice details in order to have this detail.
