Elderly man waving goodbye at rural train station AI Image Prompt

Create a realistic documentary-style photograph viewed from inside a train carriage looking out through an open doorway at a quiet rural Japanese train station platform. An elderly Japanese man, late 70s, stands on the platform slightly left of center, facing the camera with a calm, faintly melancholic expression. He raises one hand in a gentle goodbye wave and holds one semi-transparent white plastic shopping bag in his other hand. He wears a short-sleeved beige-gray plaid button-up shirt tucked into loose gray slacks with a dark belt and a wristwatch. The foreground right edge is dominated by the dark vertical metal frame and beige interior wall of the train door, making the viewer feel seated inside the departing train. Behind him are exactly 3 visible platform roof posts, a low dark platform wall, train tracks, tactile paving, rural houses, utility poles, green wooded mountains, and an overcast pale sky. Use natural daylight, muted colors, soft contrast, shallow documentary realism, 35mm travel photography feel, horizontal 16:9 composition, no text, no watermark, no dramatic effects.
