In answer to your exercise in characterization:
I love characters that are full of details, so much so that I can imagine sitting next to them on my couch and talking to them. My big challenge in writing is how to portray all of those character traits without telling. One thing I do is write a narrative about a main character, and keep it as reference while I'm writing. It's my back sheet, and it never becomes part of my story. But without it, my characters fall flat.
Thinking of Katniss in the Hunger Games, I can see she is definitely a well defined character. Yet I don't remember anywhere the author "told" us about her. It was all shown through her actions. *Love* those books.
