Designing prompt

Prompt:
A high-contrast, long-exposure light-painting fashion portrait on black, shot in a studio with heavy photochemical grain and posterized tones. Vertical 4:5 full-frame composition. A single androgynous human figure stands centered and facing forward, full body visible, feet near the bottom edge. The figure’s face and body are rendered almost completely black (near-silhouette), with only faint cool highlights; the facial features are barely readable, giving a mannequin-like, mysterious look. The head has a smooth cap/headwrap shape with a subtle cool cyan highlight on the top/front edge.

The figure wears an oversized thick bathrobe/robe that reads bright warm yellow/cream because of intense yellow lighting and glow. The robe has a wide shawl collar, loose sleeves, and a belt tied at the waist with the knot slightly off-center, belt ends hanging down. Under the robe: black fitted leggings. On the feet: white crew socks and chunky white slip-on shoes (bulky soles), both slightly glowing/overexposed.

Behind the figure, create three thick, soft-edged glowing yellow light ribbons (light trails) sweeping horizontally from left to right, curving like flowing waves.

• The top ribbon begins near the top-left area, passes behind the head/upper torso region,
  and continues to the far right edge, thick and luminous.
• Two additional parallel ribbons sit to the right of the figure at mid-height, stacked with small gaps, also curving and fading into the right edge. All ribbons have motion-blur softness, creamy yellow cores, and gentle feathered edges, like painted light.

The background is deep black with visible fine film grain/noise texture throughout. At the bottom of the frame, add a soft teal/cyan haze band (like fog or a color-wash floor) that runs horizontally across the bottom edge, slightly uneven and blurred, giving a cool base under the figure’s feet.

Lighting & look: hard frontal flash + strong yellow cast on the robe, extreme contrast, crushed blacks for skin/body, glowing highlights, slight halation around the robe and light trails, subtle vignette. Overall vibe: editorial experimental studio long exposure, gritty analog scan texture.

Camera / framing: slightly elevated eye-level, full-body centered, minimal negative space above, more space on right where the light trails flow, shallow-to-moderate depth of field (background stays flat/graphic), no environment details besides the black backdrop and cyan base wash.

STRICT: no logos, no branding, no text anywhere.
