Visual details should carry resistance, not just surface. Instead of “a red door,” try “a red door scarred by old chains,” which suggests history, weight, and prior danger. Friction inside the image generates momentum across the sentence. When each visual contains memory or consequence, your short setting accrues depth without extra lines or explanatory asides.
Let sound hint at what the eye cannot see. A distant siren implies law, crisis, or urban density; wingbeats in rafters suggest neglect and height. Rhythms reveal social order: syncopated hammering versus regimented marching. Use onomatopoeia sparingly, preferring verbs that imply source and context, so your sound immediately deepens place and suggests narrative pressure.
These senses bypass intellectual filtering and deliver immediate truth. Diesel on the tongue, citrus on fingers, damp wool at the collar—each selects class, climate, and activity with startling economy. In 100 words, one tactile cue can replace a paragraph about weather and labor, while a single smell can imply a character’s history with the place.
