Retrato em Dupla Exposição com Metrópole Submarina

A dark cinematic fantasy sci-fi double-exposure portrait of a [young man] in left-facing side profile, occupying the left half and center of a vertical frame. His face is semi-transparent and merged with a vast [underwater fantasy city]: the eye, nose, lips, jawline, and dark wet hair remain visible, while ornate towers, bridges, glowing windows, and deep cavern architecture show through his skin and silhouette. The setting is a colossal submerged metropolis inside a blue-black ocean cavern, with monumental carved pillars, layered arched walkways, suspended bridges, cathedral-like spires, and countless tiny warm lights. A huge glowing [full moon] shines behind the city near the upper right through rippling water and mist. Features luminous crystal clusters in four areas: an orange-gold cluster at the bottom left, a purple-blue cluster on a mid-left balcony, a large purple-blue cluster on the right platform, and an orange-purple cluster at the bottom right. Three small flying craft appear throughout: one near the upper center-left with blue headlights and orange trails, one tiny craft crossing the middle-right bridge, and one near the lower left emitting a blue beam. Color palette of midnight blue, cyan, indigo, violet crystal glow, and warm amber highlights. Volumetric moonbeams, underwater haze, floating particles, glossy wet textures, gothic-futuristic details, and high-contrast rim lighting. Photorealistic facial anatomy blended with matte-painting concept art. No text, watermark, or border.
