You can place the horizon anywhere you like. Draw it across the upper 1/3, center, or lower 1/3 of your paper, for instance. Positioning the horizon low will help you create a view looking up while putting the horizon near the top will direct the viewer to look down.
You’ve probably seen drawings of a street that have the vanishing point on the center of the horizon. This creates a very noticeable narrowing of the street, which can make it easier for beginners to draw.
Perspective lines are also called orthogonal lines. You can use them as guidelines to draw other subjects in your drawing so they’re also in one-point perspective.
You can try this with other shapes. Draw the closest side of a shape and connect its corners to the vanishing point on your horizon.
You could also make a drawing of the ocean with the sun rising or setting. The sun would be the vanishing point that makes the ocean look as though it extends far away from you. Keep in mind that the subjects closer to you should be larger than the ones that are near the horizon.
Place the horizon in any part of your paper, not just in the center. You could make the horizon in the upper 1/3 or lower 1/3, for instance.
Try putting 1 vanishing point near 1 edge of the paper on the horizon and make the other point off of the paper on the horizon. To do this, make a mark on your work surface or tape down a scrap piece of paper next to your drawing paper.
If you placed a vanishing point off of the paper, you can still put your ruler on it. Pull the ruler so it stretches onto your drawing paper. Then, you can make the perspective lines.
Once you become comfortable with drawing simple shapes in two-point perspective, you can move on to asymmetrical objects.
Two-point perspective is great for drawing items in a still life or distant buildings.
For example, use a two-point perspective if you’re sketching a country scene with a barn in the distance. Use a three-point perspective if you’re drawing skyscrapers close to the viewer.
Remember that the horizon line represents your viewer’s eye level.
You’ll use this grid with the perspective lines from the other vanishing points.
Note that the vertical sides of your building or cube won’t be parallel in three-point perspective. Instead, they should slant up or down towards at an angle.
