Concept Art refers to a form of illustration or visual development that is created in the early stages of designing a game, movie, book or other creative project. It involves creating images and ideas that help convey the overall vision for the final product, often before any actual physical production has begun. Concept art can include sketches, paintings, digital renderings, matte paintings, storyboards, character designs, and more - anything that helps to communicate a creative idea or visualize an imaginary world. It is used by artists, designers, writers, directors, and other creatives as a tool for brainstorming, problem-solving, and refining their vision before moving forward with the project.
