Studio Waist-Up Portrait of Young Man with Prismatic Blue Light Trails

A photorealistic vertical medium portrait in exact 4:5 aspect ratio (matching 736x920 proportions), faithfully recreating the framing, scale, composition, and dynamic studio lighting of the reference image[span_0](start_span)[span_0](end_span). A young man is centered from the mid-chest up against a vibrant royal blue studio backdrop, strictly preserving the original 4:5 vertical proportions, blue headroom, lower chest crop, and subject-to-frame scale[span_1](start_span)[span_1](end_span). Faithfully preserve his recognizable facial identity: fair-to-medium olive skin tone, defined jawline, light chin stubble and mustache, expressive dark eyes looking directly into the camera with a calm, focused gaze, and short, curly dark brown hair with textured ringlets framing his forehead[span_2](start_span)[span_2](end_span). He is dressed in an oversized, loose-fitting plain white crewneck T-shirt with dropped shoulders and roomy sleeves; match the loose, relaxed, and roomy silhouette with natural cotton fabric draping without making the garment tight or slim[span_3](start_span)[span_3](end_span). The lighting setup features cool cyan and blue studio rim lighting along his jaw and neck, with a soft key light on his face, complemented by creative long-exposure light streaks, motion-blur ghosting, and warm orange-tinted chromatic flare trails sweeping diagonally across the left side[span_4](start_span)[span_4](end_span). Authentic skin texture with visible natural pores, sharp focus on the subject, rich high-contrast blue color grading, 8K Ultra HD quality[span_5](start_span)[span_5](end_span). Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
