The prompt

Wide shot of an old fisherman in a small rowboat on a calm lake on a bright sunny day, photoreal sci-fi, locked camera. 0–2s: bright sunlight sparkles on the water and his hat. 2–4s: the edge of an enormous shadow slides across the lake toward him. 4–6s: the vast shadow passes over the boat, the water turning dark and cold, the sky's reflection gone. 6–8s: sunlight returns as the shadow moves on, and he looks up toward the sky. Throughout: glassy water reflecting the light, distant pine shoreline, fixed camera, one continuous take.

Tip

You never need to show the thing. A shadow edge sliding across the scene sells size and threat on its own.
