A major characteristic of perspective drawing wherein the objects become smaller the farther they are from the observer:

The major characteristic of perspective drawing where objects become smaller the further they are from the observer is known as "diminishing size."

Here are the steps to achieve this:

1. Draw a horizon line: This is the line at which the sky meets the ground. It represents the viewer's eye level.

2. Draw a vanishing point: This is a point on the horizon line where all parallel lines will converge.

3. Draw the object: Start by drawing the closest part of the object to the observer.

4. Draw the lines of perspective: These are lines that go from the edges of the object to the vanishing point. They represent the sides of the object that are receding into the distance.

5. Draw the rest of the object: Use the lines of perspective as guides to draw the rest of the object. The parts of the object that are further away from the observer should be smaller than the parts that are closer.

6. Repeat the process: For each additional object in the scene, repeat the process. Remember, objects that are further away from the observer should be smaller than objects that are closer.

7. Add details and shading: Once all the objects are drawn in perspective, you can add details and shading to make the drawing more realistic.

Remember, the key to successful perspective drawing is practice. The more you practice, the better you'll get at creating realistic, three-dimensional drawings.
