Cover all the senses
Whether you’re writing your first, second, third, or umpteenth draft, editing, or revising/rewriting, make sure to include all the senses in your writing. Put yourself in your character’s shoes and see what he sees, smell what he smells, taste what he tastes, hear what he hears, feel what he feels.
As you write or read over what you’ve just written, keep a mental checklist in your mind, making sure to hit all five of the senses. It’s easy to focus so much on what a character sees or hears that you miss what she smells, or tastes, or feels. Don’t neglect any of the senses!
Covering all the senses will give your writing so much more depth, make it so much more realistic. Our senses are always on alert (unless, of course, we are sensory deprived in one area or another). Don’t let your character (or your reader) miss out on experiencing one of the senses.
