These images I can credit. The top two are taken from animator Paul Julian's illustrations for Piccolo, a book you will never see face-to-face. Thanks to Lou Romano for posting so many pages on his blog. At bottom left is Chris Appelhans' "Fantastic Mr. Fox" concept art for the movie adaptation. More of that here. The bottom right image, titled "Waterfall," is from a portfolio site I obsessively scrutinize, that of Jon Klassen. Don't miss "Adventures of Ship."
