Count Baltar with Cylons for Battlestar Galactica (1978)

a) Comparable areas. It seems that the right side of the Giger painting made use of the Count Baltar and the Cylons concept art, and he would have reversed it.

 

b) The cylon face becomes a bare remnant of a humanoid mask while Balta's face becomes a part to the far right with vertical lines and ribbing running down it 

c) The upper casing on a possible viewing screen that slants downwards towards the viewer becomes some sort biomechanic structure sloping downwards at the front of the image at the bottom of the far right

d) The cylon face might become slanting piping at the far right
