Do you wear a mask/helmet as sith ?
I always start my sith with like nothing in the face, later like chapter 1 I wear something like a breather mask thing and after that a helmet or like the one destroyed helmet.
On one side I wanna see the facial expressions but on the other side I like the whole getting wounded in battle and wearing more and more helmet stuff as the story goes on.
And I also most of the time make my sith go bald, I don't know why but a sith with hair feels weird, bald = evil or how it goes.
