My story is a YA fiction written in first-person narration. How early do you generally describe the MC? Does it matter? Can it be a few chapters before you get a general idea? The main reason I ask is that the fist couple of chapters are action-packed (escaping a burning building, finding our her parents have died, etc.) and it's not until the 3rd chapter that there's room in the narration to give a general explanation of what she looks like. The first chapter covers her age and gender through dialogue between a fire fighter and a paramedic and we also learn her first name. Other than that, we don't get character attributes until the 3rd or 4th chapter and even then it's kind of vague (long brown hair and boring brown eyes [she's talking in comparison to her best friend who is green eyed and auburn hair]) other than her thinking she's "freakishly tall" again in comparison to her best friend who is petite and fine boned. The height is important to the story because she finds out she is a descendant of an Amazon race. Thoughts?
