Simon Bisley - Heavy Metal Original Concept Art - FAKK2

I believe Bisley had done 5 of the prelim or concept art for Heavy Metal in large size thin drawing papers at that time

I have doubts if they had been published before but they were being published in the Art of Simon Bisley, which I have included as additional pictures for this post

I believe the concept of this piece has later turned into a painting - which is in Printz’s gallery

A few years back, I had a discussion if Bisley could rework on this piece; which I believe would make a great painting; The idea was however being dropped later due to works & the thoughts of maybe better to keep this piece as original as possible :)
