Cinematic 16:9 YouTube thumbnail. Dynamic medium close-up of the main character from the reference image on a dark foggy lakeside quay at night, looking back over his shoulder in sharp paranoia. A harsh yellow street lamp casts stark cinematic shadows across his face and coat. Cold fog and water reflections in the background. Massive high-contrast text across the top: 'DO NOT TRUST IT' in bold distressed red-and-white letters. High tension thriller aesthetic, powerful emotional hook readable at small mobile preview size.
