What are four types of drawing?

Hi,

There could be more than four kinds of drawing.

To my knowledge the different types of drawings are:

Life Drawing  Drawings that result from direct or real observations are life drawings. Life drawing, also known as still-life drawing or figure drawing, portrays all the expressions that are viewed by the artist and captured in the picture. The human figure forms one of the most enduring themes in life drawing that is applied to portraiture, sculpture, medical illustration, cartooning and comic book illustration, and other fields.   Emotive Drawing Similar to painting, emotive drawing emphasizes on exploring and expressing different emotions, feelings, moods, self, time, etc. These are generally depicted in the form of a personality.   Sketching Sketching is a kind of drawing that puts forward the instant thoughts of an artist. Thus, it is a rough freehand and loose drawing which is not considered to be a finished piece of work. Sketching, usually, results out of visualizing and immediately capturing them onto paper.   Analytic Drawing Sketches that are created for clear understanding and representation of observations made by an artist are called analytic drawings. In simple words, analytic drawing is undertaken to divide observations into small parts for a better perspective.   Perspective Drawing Perspective drawing is used by artists to create three-dimensional images on a two-dimensional picture plane, such as paper. It represents space, distance, volume, light, surface planes, and scale, all viewed from a particular eye-level.   Geometric Drawing Geometric drawing is used, particularly, in construction fields that demand specific dimensions. Measured scales, true sides, sections, and various other descriptive views are represented through geometric drawing.    Diagrammatic Drawing When concepts and ideas are explored and investigated, these are documented on paper through diagrammatic drawing. Diagrams are created to depict adjacencies and happenstance that are likely to take place in the immediate future. Thus, diagrammatic drawings serve as active design process for the instant ideas so conceived.   Illustration Drawing  Drawings that are created to represent the lay out of a particular document are illustration drawings. They include all the basic details of the project so concerned clearly stating its purpose, style, size, color, character, effect, and others.
