Chalkboard drawing

The prompt

A chalk drawing on a dark green school chalkboard that fills the whole frame: the girl, the plants, the pots and the city skyline are all drawn in white and pastel chalk lines with a dusty, grainy texture, the green board showing through every stroke, shading smudged in with a finger, faint ghosts of erased drawings, chalk dust drifting off the lines as they are redrawn slightly each frame. On a rooftop garden above a city in late-afternoon sun, a chalk-line girl with short hair and a yellow chalk T-shirt waters potted tomato plants with a chalk-drawn 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 a few blue chalk droplets fall onto the leaves. 2–4s: a white chalk 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: everything stays dusty chalk on a dark green chalkboard, smudged and faintly ghosted, one continuous take.
