Why is Perspective Important in Art?
Perspective is an art technique for creating an illusion of three dimensions on a flat surface.
Horizon
The horizon is a line on eye level. But in art it’s the line on the eye level from the artist. So a fixed line in the art piece. It is easy to find by following architecture, tables, windows etc. But in a human drawing there is also perspective. Try looking around and determining if you are seeing an object from above or below.

Vanishing Point
The vanishing point is the place where parallel lines appear to come together in the distance. I call them V. A piece of art can have more than one vanishing point.
Types of Perspective:
One point perspective Horizon and 1 vanishing point

Two point perspective Horizon and 2 vanishing point

Three point perspective Horizon and 3 vanishing points

Four point perspective Horizon and 4 vanishing points

Photo perspective Horizon and round lines to vanishing point

Perceptive perspective Horizon and round lines to vanishing point, bends more by the horizon. The back is straight.

Reverse perspective Opposite of a horizon

Parallel perspective No Horizon

Aerial or Atmospheric perspective Colour will be softer near the horizon. Sharper the father way of the horizon
