my favorite illustrators that i’ve come accross is a japanese man by the name of Kawaguchi Youhei. he has a unique cartoonish style that I haven’t really seen before. he does characters from video games such a pokemon and other animated games. this is my favorite one from his: i love the background and the bright teal colors that stick out and move your focus around on the image.

those are three of many illustrations that stick out to me; the flow is very nice and keeps you looking at all points of the image.
