I've had the same experience as momodot watching others do drawing and portraiture. I never have the same face appear over and over by accident because all my characters are based on specific real people. I have been known to use certain favorite ones several times deliberately, exploring their many possibilities. Last week I was fiddling with FaceGen and was thinking Vincent Price real hard. If I do that, he is not about to look like Boris Karloff by mistake. If you specifically want Jessica Alba, and think about her real hard (no dirty jokes please) she is not going to accidently look like Jennifer Lopez. Oops! Bad example. -She is not going to accidently look like Nicole Kidman!
