Totoro is the mascot for Studio Ghibli, which was founded by Hayao Miyazaki. He was featured in one of Miyazaki's films, My neighbor Totoro, which was a huge hit. His main audience is towards anyone who enjoys Miyazaki's films.
Could be inspiration for an art project where kid's painted a Miyazaki inspired picture or design and then place a pre cut out character shake over the painting. My Neighbor Totoro such a gorgeous film, and now this beautiful piece of artwork.
