This is another piece I did circa 1990(ish) for West End Games' Star Wars RPG. The assignment was to show what a freighter like the Millennium Falcon looked like in it's stock form. The main things I did to the design was to:
a) Replace the upper turret with avionics systems.
b) Close up all the open hull plating that we saw on the Falcon.
c) To add strap-on cargo pods to the upper surfaces to expand the ship's carrying capacity.
This image also reproduces the pencil doodles for the art and design department that lightly accompanied the finished art. Personally I do like this later interpretation better, as it shows a great departure from the lines we recognize as The Falcon: [link]
