The image on the top is from Moebius a french Illustrator that I recently found. I love the colors he uses, the comic finish, and the beautiful landscapes that he depicts. You can see these images and more! in this link > Artist of the week: Mœbius
which is a website where you can find awesome images of different illustrators. I think it is good for inspiration and references!
I also share the main page just in case you want to see more > https://characterdesignreferences.com
Did you know about this page? Was I the only one who didn't know about this resource? haha
