Futuristic Blue Neon Teen Portrait Poster

Design a high-end dark teal and obsidian movie-style poster showcasing a trendy adolescent male youth named Piyush Barnwal, maintaining identical facial authenticity across all featured angles. The primary focus is a central headshot featuring tousled wavy locks, a dark loose-fitting button-down, a metallic neck chain, and dark shades resting atop his head. Flanked by four creative auxiliary monochrome portraits displaying diverse candid emotions and varying perspectives. Enhance the futuristic atmosphere with luminous cyan glowing trim, hazy vapor wisps, floating luminescence motes, gentle illumination rays, and an evening metropolis skyline setting.
