"Helpful Hints" to enhance your descriptive powers: (Step 3)

• Spend as much time as possible "free writing" about the image. You can always edit this down if you feel that the writing is stale or redundant. Free writing is best done with fresh eyes as a first response, and can be edited after you know the image well.
• When describing colors, expand your vocabulary. There is no such thing as pure yellow. Maybe you mean lemon yellow or canary yellow or cadmium yellow or saffron. But stick to colors that your audience will be able to visualize. For example, I can't picture alice blue, but I can picture aqua and royal blue.
• If the image is particularly abstract, focus on the emotions that the artist is trying to express. Do the lines create a sense of movement? Does the painting seem to speed up time, or slow it down? Ask your self creative questions and answer them.
