Hyur Midlander female faces need... help.

It might be clearer if you look at character creation. Face 5's eyes can be almost freakishly huge (link) with the widest eye option, which is noticeably larger than the widest eye for face 1 (link).

I've just gone into the character creator and flicked back and forth between faces 1 and 5 for each eye shape setting. The eye sizes and shapes are basically the same except that 5 has more under-eye makeup and dark eyeshadow extending from the outer corner of the eyes.

However, face 5's actual face is smaller so the eyes look proportionately slightly bigger – but also further apart.

Personally I prefer face 1's design. The shape of the eyes looks better to me.
