A lot of writers, particularly beginners, tend to waffle on ad nauseum about the trees and the grass and the rocky path - when the hero's being chased by savage wolves. I have the opposite problem. My style (and voice?) has become short. Like, I won't stop to describe anything. Well maybe not nothing... but I am sparse with everything, tending to skim over as if it's one of my plot-summaries. I've gone the opposite way. My first 'novel' ended up being only 25,000 words, thanks to this. In an effort not to become obese, I've made my writing anorexic. I squeeze all the sustenance out of it, that's what I fear. Considering it's a fast-paced action-plot in a post-apocalyptic ruin, with bullets whizzing everywhere, it's good to be lean - but the buff kind of lean, not the twig type. Right? Is there a checklist for what a short and punchy style should and shouldn't include?
