3:4 Vertical 4K-resolution Poster for a Surrealist Fantasy Exhibition

Design a 3:4 vertical 4K-resolution poster for a surrealist fantasy exhibition, featuring a luminous gradient twilight background blending misty lavender (#D6C8E7) into twilight indigo (#3A2E5F). At the core of the poster sits an elaborate 3D floating orb that resembles a celestial planet. Its dark obsidian surface is adorned with glowing streams of molten gold that form intricate rivers. The orb emits a soft, mystical radiance that seamlessly merges with the gradient backdrop. Ethereal lighting accentuates the orb’s golden channels, creating iridescent reflections in the surrounding air and a dreamlike prism-like effect. Delicate, wispy translucent clouds gently spiral around the orb, faintly catching the light and enhancing the fantasy ambiance. The overlapping text interacts dynamically with the visual elements surrounding the orb: • Behind the orb, the main title reads “DIVINE SEQUENCES” in an elegant serif font of metallic gold. Letters partially obscured by the orb appear subtly distorted, mimicking the effect of its gravitational field. • "DIMENSIONS UNVEILED," the subtitle, appears in futuristic sans-serif font rendered in platinum silver, positioned near the bottom center of the design. The glowing molten rivers subtly illuminate sections of the subtitle hidden below them, as though reflecting their radiance. The composition strikes a captivating balance between intricate visual details and expansive open areas, offering a harmonious blend of depth and focus that utilizes a high dynamic range.
