Creative work is a broad term that encompasses many different types of activities. ART, opus, and DESIGN are all forms of creative work. ART is the expression or application of human creative skill and imagination, typically in a visual form such as painting or sculpture. An opus is a musical composition, especially one considered to be of great importance or of a high standard of excellence. DESIGN is the ART or process of planning and creating something, typically a piece of architecture or a system. All three of these terms can be used to describe creative work.
