[@AngelofOctober][@Neo Is Delight] That was all very tongue-in-cheek. I'm aware what a loli is and don't think for a second I don't love the characters we're getting. I've been impressed. It was just a note than we have a lot of characters (so far) younger than Rosai, who's in the middle of the age range. I apologise if you think I was insulting your creativity.

[@pandapolio] I'll get to you later.

[@AngelofOctober], I'm an editor for a newspaper. I more often than not have to cut articles down to the core, relevant parts. There's a fine line between "relevant background" and "interesting background". In your case, you have a firebender who lives on a farm and sells wares in Ba Sing Se. That he sells and makes jewelry is relevant (why is he on the train to Ba Sing Se?). That he makes the jewelry by melting rocks he finds lying around is interesting but not relevant. 

Broad strokes takes it down to the minimum. Even with your two more points, you have six lines of data, rather than a short story's worth. That's what broad strokes are. You asked, I gave, but your character is fine as is.

Also, none of what you wrote is "showing" the audience. The dialogue is, but [I]as an editor[/I] I would have cut it out. [B]I am not telling you you're wrong.[/b] You do the showing in the IC, if it becomes necessary. Flashbacks are your friend.
