A maze or labyrinth is a popular subject for drawing exercises in parallel perspective. A good floor plan helps to depict the maze (labyrinth) from different perspectives. Such a floor plan can be drawn quickly using graph paper.
On my channel "Art with TeachANies," you'll find videos about the knowledge behind good drawings. Based on art lessons from grades 5 to 13 in all types of schools, I explain how perspective drawing works with 1, 2, or 3 vanishing points, or even parallel lines, color theory, principles of composition, how to find and use contrasts, and how to create analytical sketches.
