@Amanda-Bancroft wow sounds way cool! I hope you don't mind me tacking my 3pp guest request onto yours, i havent known where to suggest it, but this is as good a place as any.
GUS GORDON! he is an Australian illustrator, and more recently author-illustrator who works mostly with watercolor and collage and puts things together in photoshop. He has a graphic novel commissions out in 2025 sometime, Into The Bewilderness, (heres a great article that even includes his artwork from his pitch to the publisher)and i think he would be very open to doing a podcast close to release, as he has done 2 or 3 podcasts with Australian podcast “words and nerds” by dani vee. It is his first graphic novel and i think he would have a lot of interesting things to say about the experience as well as more broad topics like illustration careers, living in another country and that experience with publishing, and how he feels about art for children. Idk, reading his book finding francois really unlocked something in me because of how flat the characters are and how three dimensional the backgrounds are and how every bit was so interesting to look at because of the variety of textures and interesting integrated collage elements. He is my hero!
