I just finished reading Vol I. It's not that I am a slow reader but I simply had to stop to admire the art and patterns on some of the pages. I liked it so much I even read the Supplement!
This comic is what I feel comics should be - as few words as possible, let the art do the talking, words should work together with the art and not distract from it.
Kudos, Reimena on a superb book.
