There is something about this game that has been bothering me slightly since I started playing it way back, halfway through Arc 1 and I've finally figured it out.
Every character has slightly closed eyes which makes them look like they are high, drunk, or exhausted all the time.
You are correct. I dont want the models to have the constant "deer in headlights", 1000 yard stare on their faces. Their eyes are relaxed, and it is certainly on purpose.
