AI Prompt for a 19th-Century Railroad Scene with Dramatic Figure and Golden Spike

"Create a photorealistic historical scene in a wide, cinematic 19th-century style: {argument name="central figure" default="an elderly bearded man in a black frock coat and tall top hat"} stands dramatically at the center on a rough wooden railroad track, legs spread in a triumphant pose, raising {argument name="raised object" default="an oversized sledgehammer"} high above his head with both hands as if about to drive the final railroad spike. Around him are exactly 22 visible onlookers, mostly men in Victorian-era suits, waistcoats, bowler hats, top hats, cowboy hats, and one blue military officer uniform, arranged in a semicircle on both sides of the track; several hold canes or walking sticks, and some faces are partly obscured at the edges. In the foreground, steel rails curve inward toward a bright golden ceremonial spike or coupling fixture positioned between the rails. The setting is an open, arid plain with sparse scrub, backed by a majestic range of snow-covered mountains under a clear pale-blue sky with wispy clouds. Use realistic lighting, crisp documentary detail, slightly humorous surreal scale for the raised hammer, natural earth tones, black and brown period clothing, and a sharp focus on the central pose, resembling a staged commemorative photograph of the transcontinental railroad ceremony in {argument name="historical era" default="the late 1800s"}."
