When I think in a real Space Jockey, I am actually thinking on this:
and not on this 
Similarly, I imagine the Jockey's xeno-offspring be more like this:
rather than this...
I mean.. Do people really think that an Space Jockey would have skin
That's like not understanding the concept, pretty much like when people sometimes take in a very literal way the genetic traits inherited from a host in the Alien. I'd say it's even hard to conclude that the Space Jockey had legs. I've even come to think of something surreal, such as the living vortex or fractal-like creature from the movie Annihilation. A really otherworldly entity capable of manipulating matter on the atomic scale and creating complex forms of artificial life. Or even a life form capable of manipulating the space-time itself. It may sound like God-like powers, but still cool in my opinion.
