A Question about Rewriting

This isn’t a post so much as me asking for advice. I hope folks don’t mind.

I recently started rewriting an old story, a story that I started in college (that’s 16-18 for folks outside of the UK) and only finished in 2012 as part of my NaNoWriMo for that November. The rewrite was inspired by the picture, left, on Tumblr of a Muslim Beauxbatons student, by Celeste Doodles. (If you click on the image, it takes you to the page of the original picture). It got me thinking about my FMC in the story and her appearance.

Now, I have thought about rewriting the story in question a few times, mostly through changing the FMC as well as some other characters but none of the angles seemed to work. As I said, when I saw the picture, it got me thinking about the FMC and her appearance in the first instance. I considered giving her a headscarf and then thought, why is she wearing it. The reasoning I have come up with since after talking to others for her headscarf is to do with vanity but I am also considering maybe giving some underlying spiritual reasoning. (She’s not going to be Muslim as she lives in another world to our own).

From this, my mind turned to other aspects of the character in general. That led to me reconsidering other parts of the story and the new set up that I have developing from those decisions makes it fairly far removed from the original story that I had written over the years.

I know changes to characters and the story are normal during the rewriting process but I am wondering how big changes to the story a writer should make from one draft to another? Should they be far-reaching, heavily changing lots of aspects of characters/story all at once or should the changes come slowly and be introduced slowly over a succession of drafts?

Curious to how others view this issue as I am a little intimidate with how big the changes are whilst also being comfortable with it. It’s crazy.
