This is Ed, a super realistic face digitally rendered using Lightwave, Sculptris and Krita by Australian artist Chris Jones. I say super realistic, but you can easily tell it's fake because it's just a floating head -- there's no body. Nice try, but that's a dead giveaway, Chris.
Keep going for a demo of the face and a BONUS eyeball-only version.
Thanks to Jay, who agrees the easiest way to tell a real face from a CG face is whether or not you're watching it on a computer screen.
