Can you guess which face is real and which is computer generated?

On "Which Face Is Real?", you'll be presented with a photograph of a real human being and a computer-generated face. Can you guess which one is real? I made 8 correct guesses out of 10 and based my guesses on the realisticness of the people's eyes. The look in the eyes of the computer generated image usually feels a bit uncanny looking to me, and I'm able to tell the difference between the real and fake image this way.
