Vertical Poster with a 3:4 Aspect Ratio and 4K Resolution

Design a vertical poster with a 3:4 aspect ratio and 4K resolution, featuring a minimalist avant-garde aesthetic for a technology exhibition. Use an ultra-light teal background (#EAF7F7) as the base color. At the center, place a polished chrome 3D abstract infinity-shaped loop adorned with faint textural scratches and fine iridescent reflections. This loop displays a metallic gradient transitioning seamlessly from Electric Blue (#0077FF) to Soft Lavender (#D0B3FF), creating a shimmering effect. High-position rim lighting adds subtle prismatic shadows and a gentle luminous aura to the composition. The loop interacts with the text elements, causing parts of the letters visible through its hollow sections to appear slightly distorted with lens-like warping. • At the center of the design, showcase the main title: a bold, modernist Sans-Serif “NEXUS” logo in Electric Blue (#0077FF), partially warped and distorted by the loop's surface. • Directly underneath, include the subtitle “CONNECTING DIMENSIONS” in a sleek, ultra-thin italicized font colored pure black. Sections of the subtitle that overlap with the loop's hollow portions are warped, while the rest remains crisp and sharp. The poster layout emphasizes a balanced interplay between negative space, sharp visual elements, meticulous alignment, and advanced light effects.
