You might want to adjust your monitor/eyes if you can't see nostril hair on the right hand side!
You're right that that's another give-away, though, as the hair on the left looks far more realistic.
Lips are by far the hardest thing to animate. There's about 20 individual muscles that directly affect the shape of the lips, and then there's the 3 degrees of freedom of the jaw bone on top. And their moist nature means they stick together and peel apart as they move. Horribly complicated.They never seem to get teeth and the inside of mouths right in these things and for some reason I find that really distracting.
