Answer:
A thumbnail sketch is a small, quick, and rough sketch used to capture the basic essence of an idea or concept. It is usually a simple and simplified representation of the subject, often done in a small size, hence the term "thumbnail." The purpose of a thumbnail sketch is to serve as a preliminary visual exploration or brainstorming tool. It helps artists, designers, and creatives to quickly generate and refine ideas, compositions, and layouts before investing time and effort into creating a more detailed artwork or design. Thumbnail sketches provide a visual framework and allow for experimentation and iteration, enabling the artist to evaluate different possibilities and make informed decisions about the final artwork or design.
