It was McQuarrie's concept art that twigged me onto Star Wars in the first place (Lucas? isn't he the guy that did American Graffitti?  What makes him think he can do Science Fiction?) because the visualizations were waaay above the curve...

Always looked for his work whenever I had the chance.  Even went out and bought the Ralph McQuarrie Star Wars action figs.  You're only dead when you are forgotten, he'll be remembered!
