Vertical Poster for a Surrealist Architectural Exhibition

Create a vertical poster for a surrealist architectural exhibition with a 3:4 aspect ratio and a 4K resolution. Use a warm sandstone beige tone (#F5E6D3) as the background. Position a breathtaking centerpiece in the middle: a monumental staircase twisting in the form of a Möbius strip. The staircase, crafted from translucent marble with gentle golden (#FAD78D) and ivory (#FFFFF0) veining, appears to hover weightlessly. Its infinite loop defies gravity, with gleaming edges that capture and reflect light. Illuminate the scene with diffuse lighting that originates from an unseen source located in the upper left corner. Let this create elongated shadows in soft peach hues and a subtle glow across the staircase. Add warm ambient light beams streaming downward to provide depth without dominating the design. Incorporate abstract geometric elements—such as triangles, spheres, and arcs—that integrate seamlessly with the staircase. Arrange them asymmetrically, using brushed metal textures that alternate between matte silver (#D3D3D3) and bronze (#BB8357). These metallic forms should play with reflections and surface finishes. Float text subtly along the staircase: • Use a refined, italicized serif font rendered in brushed gold to showcase the title “ASCENSION.” Place the lettering prominently on the marble structure, giving it a faint luminescent effect to unify it with the staircase’s translucent material. • At the bottom-right of the staircase, add the tagline “beyond the horizon” in a clean, all-lowercase sans-serif typeface in deep charcoal black (#333333). Wrap portions of the tagline gently around the staircase’s curved form. Let the overall aesthetic balance simplicity with allure, utilizing stark contrasts, intentional asymmetry, sophisticated textures, and a masterful interplay of colors.
