a) Two panels featuring the space Jockey from "The Alien" in Aliens Platinum Edition, April 1992, illustrated by Tony Akins and Paul Guinan, (I don't know if it was coloured in for the original comic book or done at a later date since I can't find my copy of the original comic book)
b) Jorge Camacho's El sueño de Sancho (The dream of Sancho) (1978)
For some reason, I have the impression that this curious painting inspired the space jockey in this comic book and the colourist used it. If that was not the case, then it's a sort of mystery.
It's curious to see this paintings elephantine head in the centre, and the artist does these humanoid heads with elephant like trunks in more than one picture, but it's interesting to see this one and it was done the same year that Alien was made.
By the time of this painting, Jorge Camacho had moved from Cuba to Paris
So I am comparing the painting to the coloured-in version of the Space Jockey
In Camacho's painting the eyelids are orange , while in the illustration, the eye lids are a not too dissimilar colour.
e) The upper par of limb on the right painted ochre and yellow becomes the right shoulder and upper arm.
h) The area with Sancho Panchez merged with the clock becomes the lighter part of the space jockey's face, with the sides of the hat becoming the pale brow, with the orange head and clock body becoming the nose area and pipe. The orange phallic form become the red tone on the side of the trunk
i) We can look at how this the strings or wires connecting to the orange head from a handle become the lower arm on the left with the hand blocked out of the view by a man's head.
