When developing your characters, do you see them as people you know (personally or celebrity) or do you imagine a person whom you have never seen? It seems that I am inclined to the former. Pretty much all of the story-telling I've attempted has had characters which I have envisioned in my mind to be actors or other celebrities. Strange, but surely not too uncommon. Do you think this promotes or stifles (or has little effect on) a character's development?
