Create a 15-second, 16:9 live-action and hand-drawn doodle composite. First-person smartphone footage in one continuous handheld take, set in a rain-wet Busan harbor alley at blue hour. The real world remains fully photoreal; only the drawings are animated. No external assets. Preserve throughout: the photoreal right hand, dark navy rain sleeve, paint-stained fingertips, small cream pocket sketchbook, short cobalt wax pencil, thin wrist cord, natural hand anatomy, and consistent wet reflections. The doodles use imperfect cobalt-blue pencil lines, variable pressure, doubled contours, open gaps, loose hatching, subtle line boil, and flat transparent color. They must look freshly drawn by hand, never like polished digital stickers. [0–3 seconds] Close POV while walking. The hand draws a tiny sailboat inside the damp sketchbook. Show every stroke forming in real time: hesitant curves, overlapping corrections, graphite crumbs, and pressure changes. The finished boat wiggles, climbs over the page edge, and slides toward the ground. [3–6 seconds] The camera dips quickly. The doodle boat lands in a shallow stream beside the curb, creating a real circular ripple. Loose wave lines unspool behind it as it sails beneath a real fishing crate, becoming correctly hidden by the crate and pedestrians’ legs. [6–9 seconds] A passerby’s boot splashes through the water. The doodle bends with the ripple, smears across the wet asphalt, and briefly breaks into rough fragments. Each missing section visibly redraws itself stroke by stroke as the boat continues moving. [9–12 seconds] The boat enters a wide puddle reflecting the harbor sky. A single line grows from its mast and rapidly sketches the loose outline of a huge doodle whale across the reflection. The whale rises out of the puddle like flexible living ink, passing behind a parked bicycle and in front of distant lights with correct depth and occlusion. [12–15 seconds] The camera tilts upward as the flat doodle whale swims between the photoreal rooftops. Its tail movement makes real hanging tarps flutter and disturbs the puddles below. It exhales a playful burst of tiny scribbled fish, then holds as a trembling unfinished drawing while the real alley continues moving. Raw rear-camera phone footage: begin in close focus on the sketchbook, dip rapidly to knee height while following the boat, then perform one energetic upward tilt after the whale. Include walking bounce, slight arm sway, delayed autofocus, exposure breathing, raindrops on the lens, and subtle rolling-shutter distortion. Maintain one continuous spatially coherent camera path. Cool blue-hour ambient light with warm harbor lamps from one consistent direction. Real surfaces show natural wet reflections and soft shadows. Keep the doodles flat and unlit, but anchor them to surfaces with correct perspective, parallax, contact, reflections, occlusion, and water distortion. One uninterrupted take with no cuts, transitions, or time jumps. Every doodle must originate from a visible pencil stroke or an existing drawn line—never pop into frame. Do not transform real objects; the drawings inhabit and interact with the unchanged live-action world. Audio: light rain, harbor water, distant gulls, footsteps, wax-pencil scraping, paper friction, the sharp boot splash, wet ink smears, and a deep papery whoosh as the whale rises. Keep all sounds spatially matched to the camera. BGM: an original 15-second cue, 70% quiet wonder and 30% playful curiosity. Use muted marimba, soft plucked strings, and a warm airy pad. Stay sparse for 6 seconds, swell gently as the whale forms at 9 seconds, and hold the final 2 seconds on a weightless chord. Do not imitate an existing melody.
