How do old people draw simply and beautifully?

The steps are as follows:

Tools/raw materials: pen, paper

1, draw grandpa's head first. His hair is bald, only on both sides. He wears reading glasses and has a beard.

2. Then draw the body of the old man, wearing a shirt and sweater, standing with a big belly and hands and feet together.

Let's start drawing. Let's paint the old man's glasses brown and his skin color, hair and beard gray.

Then paint the old man's shirt gray and the sweater lake blue.

5. Continue to paint the old man's pants brown and his shoes dark brown, and the old man's stick figure will be finished!
