I bought a couple of books yesterday, and one of them is;
Making Comics: Storytelling Secrets of Comics, Manga, and Graphic Novels by Scott McCloud.
I’ve read McCloud’s Understanding Comics cover-to-cover several dozen times ever since I decided I wanted to make comics (not to mention seriously write and talk about them), and I swear by his analytical work on graphic storytelling. Do you have any of his stuff in your comics library? You should.
