My ideas; Marvel Art Academy/Disney Art Academy 2-Classic style heroes/villains. DLC for some extra modern ones. maybe some Star Wars mixed in Yo Kai Watch Art Academy- Series so friendly for this plus it is becoming popular Nintendo Art Academy- Aka Mario, luigi, Kirby Zelda to harder ones eg. Marth, Sheik, Metroid Animal Crossing Art Academy- bit of a stretch but if they have no ideas lol
