My gut reaction is that the model does an apparently credible job of simulating faces, but cannot take into consideration their underlying biology. I would think a lot of the features these non-existent people have might be biologically incompatible for reasons we don't know. Facial features are incredibly sensitive to exposure to gene:environment interactions. So, I have doubts today they look like anyone real.
