I keep forgetting to incorporate physical descriptions of my characters. Yeaaah, that's it, I forget ... truth is I tend to get wrapped up in their internal lives and motivations, that my characters lack a certain flesh-and-blood-ness to them.
My choreography tends to feel awkward, particularly in scenes with only one character. Maybe it's something to do with the POV character not being minutely aware of her own actions, and trying to get a sense of how much needs to be described or something, I dunno.
In scenes with two people, which I find more comfortable to write, my characters keep giving each other Significant Looks, and explicitly watching each other. I know exactly where this habit comes from, which is from the context of online roleplaying, where it becomes a habit to indicate where your character's attention is, so as to give other players cues to give you information. But when I'm pulling all the strings, I don't need to do that -- characters see what they see, and it can be assumed that it's because they're looking. (I even have this one nutty scene where I specify what a character's looking at but not what she sees.)
I've got a mild case of said-bookism ... I know "said" is the great invisible word, and that often a speech tag isn't even needed, but people keep telling, explaining, etc. I think I picked this up from books I've read from a young age -- I know it's an old habit. There's nothing too exotic or (hopefully) too terribly distracting, but still. Red pencil territory (or is that "ctrl-x" in the digital age of self-editing?)
Some other random observations: I've got two main characters, a he and a she, and switch POV between them from section to section. The bits from his POV are (so far) pretty much all about him. The bits from her POV are mostly about him, too. Yet I don't want her to become invisible, or only half-developed.
I also can't seem to write in a straight line, chronologically speaking. This doesn't really bother me, except that I worry that (combined with the POV switching) it won't make very much sense to someone not living in my head, or that the chronic flashback-iness will start to seem contrived.
Anyway, this is mostly based on very raw drafts, and I've tried to address some of these issues while rewriting. Some are more easily fixed than others, but there's definitely value in getting something down on paper, and fixing later.
Anyone else have habits they've noticed themselves falling into, that they have to watch out for when they're editing?
