A young man stands on a rooftop with a monster can.

"A candid nightlife portrait of a young man with short, tousled black wavy hair falling over his forehead, looking at the camera with a cool, calm, slightly serious expression and his head tilted a little. He holds a black energy drink can with a green logo in one hand, while his other forearm rests casually on a glass railing. He wears a loose off-white linen button-up shirt with a chest pocket, open at the collar with sleeves rolled to the forearms, and black jeans. The setting is a rooftop lounge party at night, with a dark sky, a draped white canopy lit in vivid pink, purple and blue, silhouettes of guests mingling in the soft-focus background, distant city lights on the horizon, and a glowing yellow lantern light on the railing in the foreground. Vibrant neon pink and blue ambient lighting, warm yellow accents, direct soft flash lighting the face and shirt, glossy skin highlights, moody party atmosphere, shallow depth of field, candid social-media style, shot on a smartphone, vertical 4:5 aspect ratio, sharp focus on the subject." Tips: Add "photorealistic, night party photography, colorful bokeh lights" for a more authentic feel. To avoid brand issues, say "a generic black energy drink can" instead of a recognizable logo. For a more cinematic mood, add "neon glow, deep shadows, subtle film grain." 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.
