The problem here too, is that they’re trying to create the uncanny valley, rather than create a non-human human.
I suspect that we fall into the valley when we commit to trying to make a human image but fail. And it has to do with humanistic movement. We never look at a painting or photoshopped image and think “Uncanny Valley”. We think, “Bad Painting” or “Distorion”. It’s not until we see a character’s movement and are asked to see something as human, that we can tell, somehow, that it’s not. For example, the speeder race on Endor in Star Wars Return of the Jedi or The Rocketeer. I can’t see how transitioning a face from a cartoon to a photo would reveal the UKV.
