Cannabis Works contains illustrations, sequential comics, storyboards and sketches. Tatsuyuki Tanaka is good at drawing cyber fantasy, weird robots, mechanical stuff and complicated backgrounds. His colour palette is unusually muted with a focus on earthly tones, giving most of the illustrations an aged and, sometimes, eerie otherworldly effect.
Every single piece of art in the book is new to me. I've never seen any of his work before and this book is an eye opener. There are plenty of storyboard sketches which look like they are created for animation, but no titles come to my mind. I'm missing out on a lot of good stuff.
I've nothing much to add other than it's well worth my money, especially for the sketches.
