I wonder have the reconstruction techniques been verified by a double-blind experiment to reconstruct the face of a homo sapiens from a skull with a known photograph. Otherwise, you're just wondering how much of it is just artistry and how much solid, verified technique.

Even that has the problem of assuming that they're basically human - similar to the artist's depiction of a cat from it's bones: https://static.boredpanda.com/blog/wp-content/uploads/2020/0...
