The Halo 4 Cortana is in my opinion the most beautiful version. I just love her complexion. Omnine on Deviant Art gave her a human skin tone in this picture. I think she looks even more beautiful. You know when I think about it, this Halo 4 Cortana version is the best animated video game character I have seen so far. The amount of emotion and life in her face! Ahhhh, I wanna marry her.
