Anime Drawing Lessons for Pre-Teen

My 11 year old son really wants to learn how to draw anime - freehand and digitally. He's been learning on his own by watching Youtube videos, but I would like to find a class for him. At this point, he's not interested in drawing other things (nature, still-life, etc.), though I hope his interests in drawing anime will lead to other subject material and other types of art. I see in an older post that I might be able to find a tutor from CCA, but I'm hoping for a small class with other kids. If there are other parents with similarly-aged kids who would like to form a small anime drawing class and find a teacher, I would be open to that too. Thanks!
