Charcoal / pencil sketch

The prompt

Charcoal and pencil sketch animation on off-white paper: dynamic, messy graphite and charcoal lines, cross-hatched shading, visible smudges and eraser marks, the lines redrawn slightly every frame so the drawing boils and shimmers. On a rooftop garden above a city in late-afternoon sun, a girl of about ten with short brown hair in a yellow T-shirt waters potted tomato plants with a small tin watering can. Medium-wide shot at her eye level, three-quarter view, the camera holding still. 0–2s: she tips the watering can over a potted plant and water splashes onto the leaves. 2–4s: a white paper airplane glides in from screen left and lands on the rim of the pot beside her. 4–6s: she sets the can down, picks up the paper airplane and turns it over in her hands. 6–8s: she looks up and out over the city rooftops and smiles as the wind ruffles the leaves and her hair. Throughout: the image stays rough graphite and charcoal on paper, the lines boiling slightly from frame to frame, one continuous take.
