Literature and many books show the value of using symbols to represent aspects of the story theme. Obviously, mood will be influenced by the use of symbols that represent each scene. But how do you use your storyform to decide where to use symbolism (or image systems)?
In Shoot Your Novel: Cinematic Techniques to Supercharge Your Writing it discusses Image Systems:
"Consider the core idea of your book. See if you can encapsulate it in a phrase or sentence. Write down words that reflect your image system. Think of how those words or ideas could be visually and symbolically portrayed throughout your novel."
My question is this: is there a certain element of the Storyform that lends itself best to these image systems? For example, is it the ISSUE? Or is it more of the PROBLEM that has a symbol?
Under which of the many elements of the Storyform do you try to have symbolism?
