Here's why:
* Characterization is about more than just describing a character's physical appearance or personality traits. It's about bringing a character to life in a story. This involves revealing their motivations, conflicts, and how they evolve over time.
* "Creating" implies that the author is building the character from scratch, defining their unique qualities.
* "Developing" emphasizes the process of showing how the character changes and grows throughout the story, responding to events and interacting with other characters.
While other phrases like "depiction of a character" or "representation of a character" might be accurate, they don't fully capture the dynamic and multifaceted nature of characterization.
