Shading is used in drawing for depicting levels of darkness on paper by applying media more densely or with a darker shade for darker areas, and less densely or with a lighter shade for lighter areas. There are various techniques of shading including cross hatching where perpendicular lines of varying closeness are drawn in a grid pattern to shade an area. The closer the lines are together, the darker the area appears. Likewise, the farther apart the lines are, the lighter the area appears.
Continuing last unit, the perspective skills. It was really helpful to draw the model or object. I can know the the structure of the object. I use quick lines to draw the structure and use pencil to make the shadow of the surface. At the beginning, it was difficult, but more practices later, I can use the skills much better.
