How do your characters cope under pressure? What support do they get from other characters, family and friends? When called to go on a quest of some sort, do their family and friends support them or think they're nuts (adding further pressure to the character)?
What is the long term consequence(s) for your main character as a result of the story they've experienced? They shouldn't be the same people as they were at the start. No change = no conflict = no story.
