I'm not unfamiliar with heavily revising existing work; actually, it's kind of my forte'. It's a special kind of fun to break down an existing chapter and build it up to something better and new. But when the foundations are just shaky enough to warrant a large amount of reshaping, yet have have enough structure to weigh against an entire re-write, it can be...trying.
But it's done, just have to give this chapter another few look-overs and nit-pick.
What'd I do? I had to rework an interaction between Jakmin and Sye that was referring back to a scene I cut out, which involved me getting creative and finding a better way to characterize the two. Involved a lot of my "think, don't tell" show method. Having a character persistently narrate their opinion and perspective fleshes them out quite well.
The more somebody talks, the more you get to know them.
I wonder how common of a process this is, to gut large portions and rewrite others of an old, lengthy work. I just can't wait to see how it shapes up so I can get back to book II
