3. Elements of Art: SPACE & VALUE
The feeling of space in a drawing or painting is always an illusion; the illusion of depth on a 2-D surface.  Artists combine the use of the degrees of light and dark value with other techniques to create the illusion of depth or volume to a subject.
SPACE! Some of these are: simple overlapping, and linear perspective.  Let’s see how each is used to create the illusion of space in flat, two-dimensional objects like paintings.

4. Simple overlapping
In simple overlapping a figure partially hides an object that’s supposed to be behind it. Since our eyes are easily fooled, we willingly agree that one is closer, the other is further away. 

5. Linear Perspective
Linear perspective is a geometric, mathematical method using receding lines called orthogonals that move toward a vanishing point.
