Create a 9:16 editorial poster based on a fan-shaped composition, with an emphasis on curved structures, flowing movement, and strong visual rhythm. SUBJECT: [Subject] TITLE: [Title] CONCEPT: [Concept] FAN LOGIC: [Fan Logic] VISUAL MATERIALS: [Visual Materials] COLOR SYSTEM: [Color System] TYPOGRAPHY: [Typography] BACKGROUND: [Background] TEXT DETAILS: [Text Details] Use the fan-shaped composition as the main visual language, but do not limit it to straight wedges. The structure can bend, arc, curve, flow, expand, compress, or rotate depending on the concept. Prioritize graceful visual movement. Let the composition guide the eye through the poster with ribbons, arcs, layered curved sections, or a single radial burst used in a more expressive way. The shape should help express the idea: * a flowing ribbon can suggest wind, motion, transition, or invisible force * offset arcs can suggest observation, rhythm, memory, or layered perception * a radial burst can suggest sound, signal, speed, or urban energy * motion arcs can suggest body movement, choreography, or time unfolding Build a strong large silhouette first, then fill it with controlled visual variety. Mix image sections, pure color areas, negative space, and small editorial details so the poster feels designed rather than template-based. Allow some elements to break across the fan boundaries when useful. Curves should feel intentional and elegant, not decorative for their own sake. Typography should feel integrated into the composition. Use one clear title, a short supporting line, and a small amount of editorial text. Keep the copy meaningful and concise. The final poster should feel like an art-forward editorial collage: visually striking from a distance, but richer and more layered up close.
