Doing a big editing project for a novel, and I'm cleaning up a lot of "soft" language in sentence structure. If you soften the sentence with "might," "could be," "started to," "seemed to," etc., you soften the stakes. This is a piece of military fiction, so these word choices echo throughout the novel.
That goes for passive sentence structure, too. Active structure moves forward. Passive structures add a tiny, unconscious pause. Tight sentences allow action and important details room to breathe, too.
Just random thoughts. I am sitting alone, after all, and the dog doesn't care much.
