Draw a big circle first, and then draw a small circle inside, as shown in the figure:
This big circle is the position range of the whole body, and the small circle is the position of the head. Then draw the trunk according to the position of the head. Parallel guide lines can help you determine the direction of your body. Give a human body center line and trim the auxiliary line a little. Then draw two small circles to represent the knees. Connect the torso and knees, add auxiliary lines, and then draw two small semicircles on the boundary of the big circle to connect the knees. This is a foot. Then draw a hand, draw two small circles on the upper part of the trunk as shoulders, and correct the shape of the trunk according to the width of the shoulders, so that the extra lines can be erased. Finally, add wrists and draw palms. Reduce the transparency and draw lines, and it will be fine.
