About this scene

Industrial-age machine shop at midnight under a single flickering candle: a novice mechanic struggles to install a gear on a vintage machine, while their scruffy dog tugs at a nearby toolbox on the floor. Props in use: workbench cluttered with tools in the foreground, vintage gear lying next to the machine, flickering candle on a small shelf, gear spanner in the mechanic's hand, leather gloves on the workbench, oil cans along the left wall, toolbox on the floor near the dog, metal scraps scattered on the floor, work logbook and pencil on the workbench, worn out boots by the door. Iridescent emerald and ruby red color palette. No signs or lettering anywhere.

Composition: top-down flat lay overhead view, asymmetric layout
