Now try drawing cubes above and below the horizon line using two-point perspective:

Above the Horizon Line: Start by placing a vertical line where you want the front edge of the cube to be. Then, connect the top and bottom of this line to the two vanishing points on the horizon line. Since the cube is above the horizon line, you’ll see its bottom face.

Below the Horizon Line: Begin with a vertical line below the horizon line to represent the front edge of the cube. Connect the top and bottom of this line to each vanishing point. For cubes below the horizon line, you’ll see the top face of the cube.

By drawing cubes both above and below the horizon line, you’ll observe how perspective creates a realistic sense of height and depth
