Hello. Sketch is the foundation of all plastic arts. If your children are sensitive and interested in art, it depends on whether your parents allow them to develop into art. If your children show talent and interest, it is recommended that your children focus on development. If you want to learn art well, you must learn to sketch. Now you are still young. You can take part in some art training (sketch training) to lay a good foundation for your future career while ensuring that the culture class will not affect you. I came from an art background and have been working for 5 years now. I hope I can help you.
