Vertical story (9:16) · GPT Image 2.5 SunburstDía de los Muertos ProcessionRead the exact prompt
Create a finished vertical social media story graphic announcing an event, in a 9:16 aspect ratio. Produce the graphic itself, without a phone frame, app interface, or mockup. Keep all text inside the middle 80% of the height so app controls do not cover it. POST TEXT Use the following event information exactly as written. The labels before each colon are for you, not for the graphic; print only the text after them. Do not invent extra event details. Title: Día de los Muertos Procession When: Monday, November 2, 2026 · 7pm Where: Garfield Square, Mission District Highlights: Candlelight procession and community altars Admission: Free · Bring a photo of someone you miss ART DIRECTION Interpret the supplied brief in CoBrA style. Visual vocabulary: childlike or mythic figures with bold outlines; vivid flat or semi-flat colour applied with visible energy; heavy gestural line that defines form expressively; animal, mask, and totemic imagery; composition without Western academic perspective. Lettering direction: hand-painted or roughly stencilled title; text integrated into the image rather than set formally. Suggested colors: vivid unmodulated colours — cobalt, vermillion, ochre, viridian, black, white. Composition: figure or figures filling the field; text in a bold painted band. Atmosphere: raw, mythic, child-like vigour, post-war energy, Nordic. Keep out of the design: Swiss or Bauhaus rational geometry, photographic realism, decorative polish, artificial yellowing or ageing. Apply the visual language to the supplied brief; do not invent historical affiliations, endorsements, or extra copy. ILLUSTRATION NOTES A tall totemic skull-mask with candles for eyes, drawn in heavy line. These notes guide the imagery; do not print them as text. This will be viewed on a phone: keep the event name very large, use few words at a large size, and leave generous margins. Keep supporting details readable with clear contrast. Check spelling and retain the supplied wording. Do not include these instructions, labels, watermarks, or extra slogans in the artwork.
