I'm most of the way through my first-pass editing of draft zero, and I've definitely learned a few things about my writing style. For one thing, I have a devil of a time remembering the full names of my characters - several of my in-line notes involve "[CHECK VERONICA'S LAST NAME]" or "[INSERT JONATHAN'S LAST NAME]." It's kind of sad, but it makes me feel a little bit better about the fact that I have a hard time remember real people's names as well - it means that, even when I make the people up, I'm just no good with names.
I've got a better idea of what needs to be fleshed out in book 1, and where to go in book 2, which is super helpful. Once I finish this pass, I want to go back to my rough outline of book 2 and fill in some of the gaps that I know need to be filled, before going to book 1 and turning my notes into actual changes in the manuscript. This, of course, is provided that I can read my own handwriting - we'll have to see about that.
All in all, I feel good about the progress being made. I'm ready for November to get here (and more than ready for the election cycle to be done and over with, with as little bloodshed as possible, please). 2016 is finally making its way into the history books, and I say good riddance.
