For fiction writers - novels, short stories, flash fiction, etc. - whenever you're coming up with a storyline and character base, where does the image of your character come from? What inspires their look? Do you use celebrities as a potential cast list or do you try to think of a wholly original, authentic face and body image? Also, is the image as vivid in your head as, say, the image of someone close to you, or is it a fuzzy depiction?
