As you dive deeper into your semester project, your character will experience a real development and arc (or at least it should). I would suggest using this look into “The Hero’s Journey” as a guide. Joseph Campbell & Christopher Vogler have provided a wonderful approach to exploring and evaluating the “Arc of the Protagonist” and the impact of secondary characters. There is also an interesting perspective on “the journey” itself.
This guide is a must for anyone interested in understanding “character.”
