I got the final scene written this morning. Now I let it ferment for a week or so and begin some serious revisions. Some of what I've got is pretty much what I wanted it to be, but there's a lot of work that needs to be done to make the good stuff even better.
I struggled with the opening couple of scenes, so I need to really tweak those. And the ending (what I wrote today) isn't sitting quite right, but that may be because I just wanted to finish it and wasn't paying enough attention to pacing and wording and other stuff.
But the basic story is there. And I know I can make it better with objective self-criticism. It's one of the toughest parts of this thing, but I just have to approach it the way I would if it was someone else's story that I was asked to revise.
