Annotations exist to help artists express their thoughts on their work, show influences, techniques, and how they are working to improve. Annotations should explain what was done, how ideas will develop, experiences, methods, choice of materials, how works fit a project, opinions on aspects, use of elements like composition and color, and potential improvements. Artists must use proper vocabulary covering elements like line, shape, texture, and principles like balance. Annotations should be reviewed to ensure all relevant topics are covered to develop understanding.
