You're welcome! I shared from AnimationObsessive's blog, and they did a great deal of research and showed the drawing image boards on paper from Mr. Hayao Miyazaki himself and the studio. This article I find unique, and some images have not been seen or public before. I recommend subscribing to their blog for more animation articles.
also, the inaugural special exhibition for the new Academy of Motion Pictures and Sciences museum in LA was on Miyazaki; they somehow gathered all these boards and notebooks in one place for several months. This was magical, and I give the curators props for doing this; they could have easily started off with a self-celebratory American/Hollywood franchise...
But I think they released a exhibition book to go along with this that has a lot of his artwork in there as well
