Light and dark sketch cube and its steps

To draw a cube in a light and dark sketch:

1, a good grasp of perspective is a guarantee of correct modeling. Every object is in three dimensions. In order to draw a sense of space and three-dimensional sense on two-dimensional sketch paper, we must use perspective, which has the laws of near-big and far-small, near-wide and far-narrow, near-real and far-imaginary.

2. When drawing a cube, there are often three sides. First of all, we should probably lay a layer on the dark side and recognize where the dividing line between light and dark is. This picture is either rough or soft. Draw with the background. Don't use soft strokes. ?

3. Next, draw the position and size of the projection. First, draw a pencil, adjust the shape, adjust the shape, adjust the shape, and adjust the whole.
