My daughter joined the one next to Art fram - called "XXX Star"!! (forgot the name already). She was 2.5 years old. They don't teach any techniques but just asked her to copy/imitate one picture drawn by others. She didn't even know how to hold a pen and the teacher asked her to "draw a circle in the middle of a drawing paper". (She was supposed to draw a girl and starting with drawing a face first).
She has no idea of how to construct a picture!!
You better just go for a trial lesson before deciding to pay and join a whole course.
