The queue will be divided into scenes, which can be water queue, ticket queue, or stair queue.

But the most important thing is the student's sketch.

Take boys and girls standing in line alternately to buy tickets as an example. Draw the first boy in line first, draw a simple sketch, then continue to draw the second girl behind, and then continue to draw later. Remember to change the clothes, hairstyles and heights of the characters to show the difference.

Then draw different colors for the children, and you can choose brighter colors to reflect the lively age characteristics of the children.

Finally, draw a scene, draw a ticket booth not far away, and add railings to make the picture more vivid and real.
