I just picked up the ‘Art of Rogue One’ book, which is very similar in format to the ‘Art of TFA’ book. Forewords by Doug Chiang among others. He is now some VP of Creative but still picks up the stylus and contributes spaceships and monsters. Lucasfilm has a real dream team of concept artists to work on their marquee franchises; Ryan Church did a lot of work, big fan of his, and a ‘creature concept designer and sculptor’ named Luke Fisher did the big push on K-2S0. Matt Allsopp also did some spaceship work. Really cool learning about their process - these guys can really PRODUCE good work on deadline - they even did the “one minute sketch” drill on the U-Wing. Recommend the book!
