Centered giant light blue tech-inspired 3D letter "NEW" design, simplified outlines of Shanghai landmark buildings embedded inside the letters, bottom is glowing tech-inspired track lines extending to the center of the frame, left, right and bottom of the frame are adorned with rounded sphere elements of varying sizes and gradients. Scene: based on a pure deep blue gradient space, background filled with fine radial tech lines, bottom creates a glowing planar extension effect, overall is an open tech event scene, no text. Style: futuristic tech style combining flat design and vector style, with geometric 3D design, both modern and futuristic, neat and smooth lines. Color palette: dominated by different shades of blue, accented by purple-pink gradient light effects, natural and bright light and shadow transitions, overall bright and clean color palette, full of tech sense. Lighting: uses central spotlight effect, emits bright cold light from the bottom track to the central letter area of the frame, edge lines have subtle light effects, sphere elements have soft 3D shadows and highlights, distinct layers. Composition: symmetrical centered composition, visual focus concentrated on the central subject element of the frame, background radial lines converge towards the center to guide the line of sight, left and right elements of the frame echo for balance, overall open and expansive. Purpose: suitable for main visual backgrounds of AI-related summits, internet tech forums, meets the needs of creating a tech-themed atmosphere.
