Perspective is defined as a way of regarding a point of view. I have always been fascinated by the way a character may perceive a person, or a situation. I try to write with a natural perspective. How would people actually see the world around them. Each character is their own person, and I try to portray those differences whenever a viewpoint is not the main perspective.
I had a friend ask about how I write descriptions. She wondered why I introduced characters with very little detail sometimes. I explained, "Cassy is the main perspective I tried to describe. Whenever you are seeing through her eyes, she is more descriptive. I have found that women tend to be more observant and descriptive than men. Women romanticize a description more, they will visualize a scene or person to fine details. Since the other perspectives are through men's eyes, they are dismissive to minute details or aren't learning any new information, especially if they've already met the person."
Cassy, as the main character, learns information with the audience. As she explores her world and experiences new things, the reader will be opened up to the world around her. This may not be a normal way of writing in a new character, but I have found it interesting and fun to do.
Writers should never worry about the 'traditional' way of writing because it's all about letting your imagination and style thrive. Ensure that you enjoy your work, and if even one person likes the story, it's a success! That is my perspective.
