Perspective drawing is a technique used to depict spatial depth, or perspective. In other words, it allows us to accurately draw a three dimensional object onto a two dimensional plane.
One-point perspective is often used for compositions that look at objects from the front.
Two-point perspective is used for compositions that look at objects at an angle. As it is close to what the human eye normally sees, it is the most used perspective when drawing manga backgrounds and illustrations.
We practiced the skills every week, I liked to draw the room views or furnitures. These three works all use perspective drawing skills to finished lines.
