Keep in mind:
Real people are complex and have flaws as well as strengths.
Readers want to like the characters but don't expect or want perfection, just believability. They want to identify with the characters. Even antagonists need both. Most don't believe they're bad at all.Real people act, live their lives. They don't wait around for things to just happen.
Real people are fairly consistent in how they talk and react to situations.
Know your character inside and out. What motivates him/her/it? How does the character deal with obstacles? What flavor would your character order at Baskin Robbins and why? Paper or plastic?Real people are reflected in their surroundings.
Physical attributes, body language, clothing, setting and even a name or nickname can reveal character.Real people grow as they learn and experience new things.
Some don't change, but the ones that really rock do!Many writers suggest a character analysis or character interviews to get to know the character better. One piece of advice above all others that helps me the most is to think about how your other characters would describe your character. What makes him/her stand out from the others? How well do your other characters know each other? I hope something in this post will help someone in the blogosphere! Thank you all for coming by my post.
