If I had to mention a tv show that I really loved as a kid and still influences me to this day, it would have to be Adventure Time.
It shaped my artstyle a lot and sometimes, you can still find some of its influences of my work. I loved to lose myself in the mysterious land of Ooo, with its magical and sometimes dark, yet fascinating places and characters. I just loved the idea of visiting another unknown location and going on another wacky adventure with my favourite characters.
I also really loved the brother-like relationship between Finn and Jake, which is an element I really love and is also present in my story.
If I had to mention a book, though, it would've to be Geronimo Stilton's books, in particular the hero saga. I don't know if these kinds of books are produced outside of Italy as well, but I can assure you, they were really enjoyable to read as a kid.
It inspired me to take a different approach with narration and prompted me to write a hero saga of mine as a kid (which I never unfortunately completed ) and draw digitally.
