What ideas are developed in To Kill a Mockingbird about the significance of individuals perspective

The Significance of an Individual's Perspective in "To Kill a Mockingbird"

I couldn't fit the whole title in.
I am having trouble coming up with ideas to support my point and was also just looking for feedback in general. This is a 5 paragraph essay. This is what I have so far:

A person's perspective dictates almost every interaction that they have. It determines their thoughts and actions, and how they choose to express themselves. An individual's perspective is the lens through which they see the world through. A perspective is shaped by an individual's religion, family, friends, and so on. The novel To Kill a Mockingbird revolves around this idea of perspective and it's significance in our lives. Harper Lee develops the the idea that as an individual gains perspective, they will also develop empathy for others. She presents this idea through the character of Jean Louise (Scout) Finch. This concept is portrayed multiple times in the story, and is a recurring theme.

This is just my introductory paragraph, and my teacher has told me that it was too short as well. Thank you.

It is heavily redundant. You need to define the significance of perspective from the start based on:
-Your personal definition
- The dictionary definition
- Characters definition ( several, not just one character)

It is too short because you do not provide a thesis statement in the opening paragraph. What will your focus be in the essay? Whose perspectives will you compare? Why do you think these should be the comparison partners? There are several ways you can go with this essay. The problem, is that you do not have a clear thesis topic at this point. If you use the outline I provided, along with the questions I posed, you should be able to develop a longer, more relevant introduction / thesis statement.
