More Information about the technique used in the creation of this painting:

Impasto is a technique used in painting, where paint is laid on an area of the surface in very thick layers, usually thick enough that the brush or painting-knife strokes are visible. Paint can also be mixed right on the canvas. When dry, impasto provides texture; the paint appears to be coming out of the canvas. it can add expressiveness to the painting, with the viewer being able to notice the strength and speed by which the artist applied the paint. Impasto can also push a piece from a painting to a three-dimensional sculptural rendering
