you won't make yourself a name if you follow the rules

I drew concept art for the cover of novel number one. I have concept art in my head for the covers of novels two through four. I have eight thousand words of notes and three hundred words of novel. I think I may be doing this in the wrong order.

So answer in comments please:

(1) How worried should I be about making sure every instance of Rae-PoV narration pronouns referring to Rae are ze/zir instead of she/her, given that ze's female-agender genderfluid? I keep writing zir as she/her. It's a pain.

(2) When talking about Rae before ze found out about genderqueer, should I use she/her pronouns, or (since it's present-day Rae narrating still) stick with ze/zir?
