Lisa Congdon offers a “Creative Unblock Project” to explore that interplay between structure and imaginative play:
Choose one thing you love to draw or paint (and feel comfortable drawing or painting) already: an animal, object, a person, whatever. For thirty days, draw or paint that thing thirty different ways, a different way every day. You can use different mediums, expressions, positions, colors, whatever. Each day, push yourself to do something much different than the day before, but keep the subject the same. See how keeping one element constant (in this case, the “thing” you love to draw or paint) can allow you to break out creatively in other ways.
