I want to be a doll teacher, what should I learn (better)

Fashion design, makeup, in short, art is very important.

Sketching is absolutely necessary. This is the foundation of all aesthetic arts. However, you seem to know something.

I recommend you to read a book, the title of which is not mentioned for the time being, and I will lend it to you then.

If you are determined to be a doll teacher, I recommend that you learn to sketch and practice painting now, and you must have a sense of color.

In short, come on and fight for your goal!
