The evolution a piece of art takes from concept to finished work will never cease to amaze me. Each artist has their own process and work thru the composition and details in their own way and often have to incorporate changes requested by the client. Here are a few examples, the first is the Star Wars "A" one sheet, by Tom Jung, the second is the Indiana Jones and the Last Crusade one-sheet, by Drew Struzan, and the last is the cover of the comic book adaptation for Return of the Jedi, by Bill Sienkiewicz.
