Crow outside window

Use the provided reference image as the starting frame. Maintain the exact composition, environment, lighting style, and camera position throughout the entire video. Do not alter the scene design or introduce new objects beyond natural motion. Photorealistic cinematic video of a dark raven in a snowy exterior scene approaching a window. The camera remains fixed inside the room, looking outward through the glass at night. At the start of the shot, the raven is positioned at a distance outside the window, partially visible against a softly falling snowfall. Snowflakes drift slowly through the air in layered depth, moving naturally with gentle wind variation. The raven begins to move forward from its distant position, flying toward the window in a controlled, natural motion. Its wingbeats are slow, heavy, and realistic, with subtle feather articulation and aerodynamic movement. The motion is calm but purposeful. As the raven approaches, it becomes increasingly detailed and prominent in frame, eventually coming close to the glass. It lands or hovers just outside the window, facing inward toward the viewer. Throughout the motion, the raven casts subtle, shifting shadows onto the window and nearby surfaces, caused by exterior light interacting with its moving wings. These shadows evolve naturally with each wingbeat and change in position. Snow continues to fall steadily in the background, accumulating visual depth. Snowflakes pass in front of and behind the raven, enhancing spatial realism. Lighting is low-key and cinematic: cold, diffuse moonlight reflecting off snow, creating soft highlights on feathers and faint reflections on the glass. Interior remains dim, allowing the raven to be the focal point. Camera remains completely locked-off, no shake, no zoom, no rotation. 35mm cinematic lens look, shallow-to-moderate depth of field with focus shifting naturally toward the raven as it approaches the glass. Mood: quiet, eerie stillness with a sense of observation and tension. The raven feels intelligent and intentional, as if studying the interior.
