When I write, I think in term of scenes, not chapters. When I think of them as scenes, it helps me get a complete picture of what's going to go on at that moment. I don't know why chapters can't do that, too, but there seems to be some sort of disconnect between my brain and the word chapter.
Maybe one of the reasons why is because when I write the story appears like a movie in my head and I'm trying to describe what's going on in that scene. Do you write in scenes or chapters?
As for senses, I'm really trying my best to utilize every sense I can in my MS. I want people to get the way Ax feels right away. I want them to get a good picture for how it would be like to actually live in this world. That's one thing that books have over movies. Movies might paint a better picture--but a book can bring you to the world. I can describe the dullness of the world easily with just sight, but I feel like adding how the place smells and how the air tastes--the sounds and touches, the temperature--will be so much more vivid.
May seem obvious, but there are a lot of writers who skimp out on those other 5 senses. Yeah, we have them in when our MC smells some delicious food or touches something gross... Obvious places, where any other sense would make everyone go "Um... What?"
How many of you succeed on utilizing as many senses as possible?
