@intheend in my creative writing class we used character sheets. It’s all good for strictly fictional characters or characters that only have a small part in the book based on a real person. I met a challenge when basing what is going to be a main character, when I based one on Chester, even though his character is strictly fiction, some of his characteristics will be infused with the character. When I started his character sheet I was able to fictionalize him fine, but core characteristics, personality, and some other minor things was where the challenge was, or is. I was like favorite color, ummmm. So, this is what I have been researching. Chester.
