Figure paintings, also known as figurative paintings is a type of representational art where the artist holds a strong reference to the real world, most particularly to the human figure. They usually include illustration of humans in an informal situation, with no focus on the face. Life drawing, which is the typical process of learning in every art school (students depict a live model, usually nude and positioned on a raised platform), is the basis of this art form. Modern figurative has some common threads with expressionism, with as one of the most talented painter: Pablo Picasso. Its current form features a range of experimental forms, compositions and subjects. Form is one of the seven elements of art. Together with line, colour, texture, space, shape and value, they are the visual tools used to compose an artwork. As opposed to shapes, forms covers a three-dimensional object in space. It was based above all on the human body and aims to modify a natural appearance in order to create a new form that conveys sensations or meanings in itself. Geometric forms are mathematical, precise and refer to the basic geometric forms such as sphere, cube, pyramid, cone, and cylinder. Organic forms have a natural look and a flowing and curving appearance. They are not symmetrical and usually occur in nature as in the shapes of branches, leaves, clouds, animals, the human figure, etc. In drawing and painting, the illusion of three-dimensional form is created through the use of lighting and shadows, and the interpretation of value and tone.
