No I think that this skull is beyond human interaction (physically warping it), I would say that it's a human with a prominent genetic disorder.
An old friend (not really friend, just a fellow student) of mine who now lives in Salt Lake City, had a head much like that of the artist's rendition. He was a creepy little fellow. Large eyes, skinny as anything, long finger, arms, legs and toes. And a triangular head like the one in the drawing.
I dunno, I think it would look a little more decisive if a jaw was recovered.
