Everything is realistic, grounded, and aesthetically pleasing.\n\nPet:\nA [Dog] walking beside the subject. The pet’s form is natural, expressive, and receives soft directional lighting to match the cinematic tone. The pet behaves calmly, walking close to the subject.\n\nSetting:\nA beautifully cinematic environment such as a quiet evening street, a misty park pathway, a soft golden-hour field, or a lantern-lit city walkway. Warm or cool tones depending on the mood. Light mist, drifting particles, or soft bokeh enhance the storytelling. Nature or city elements glow gently in the background.\n\nCamera / Composition:\n4:5 vertical movie-frame\nMedium-distance shot showing the full walk\nCinematic depth, wide aperture feel, atmospheric haze\nNo text, no watermark"
