Executive producer Dave Filoni has said that the show's look and feel will rely heavily on the legendary vision of Ralph McQuarrie, whose contributions to the original films helped define their now-iconic aesthetic. Looking at this artwork – some of it straight from Filoni's own sketchbook – it's not hard to spot McQuarrie's influence.
