Well, as someone who writes for his own amusement more than anything else - and never hardly posts - I tend to write long stories, and when I get into a dead end, or my writing seems to be complete cack I go and re-read the parts I feel are atmospheric - if there's one thing I really strive for and believes can make a story, it's atmosphere.
I do like to put detail into stories that aren't relevant other than to add to the feeling of the main thrust of the current scene as such - but I'm a complete amateur.
I tend to draw more, and when I try to write, I'm always trying to make one scene perfectly evocative of how I see it in my head - and that means that visually descriptive scenes. That includes details of what's going on in the background to make things more realistic - I try to avoid describing how people look, or what they are wearing, I like to write what's happing around the people I'm talking about but make that indicative of what's happened or what's happening.
When that kind of detail leaves, and because I'm such a shoddy writer then my stories become a description of events. When I concentrate on detail too much, I achieve nothing and get bored of writing. I'm still toying with getting this balance right.
I'm trying a new approach right now - I'm writing something and charging through chapters at a time with how I want things to happen - the action. Then, after two or three night-sessions, I go back and pad things out. It usually means re-writing what I've already done, but not re-writing the story what I set out to achieve. By having that skeletal framework in place, I can concentrate on the story in one aspect, make sure it progresses without getting distracted. It seems to work sporadically, making some parts I'm happy with, and others that make me cringe with embarassment.
I'll keep at it
