A stylish beach portrait of a young man

A stylish beach portrait of a young man with thick, curly, voluminous black hair and a neatly trimmed beard and mustache. He wears rimless, gradient-tinted sunglasses with a pink-maroon lens and a sleeveless dark charcoal ribbed tank top with a thin silver chain necklace. One arm is raised with his hand resting behind his head, the other hangs relaxed at his side, showing a toned, athletic build. He looks slightly downward with a cool, confident expression. He stands in shallow water at the shoreline, with gentle waves rolling in behind him and calm blue-green sea stretching to the horizon. Clear pale-blue sky, bright midday sunlight, warm skin tones, vertical 3:4 framing, shot on iPhone, natural skin texture, slight sun glare, candid lifestyle photography, summer vacation mood. Tips for better results: Add "photorealistic, high detail, natural sunlight, no heavy filters" for an authentic look. Specify "portrait orientation, 3:4" in ChatGPT, or "--ar 3:4" in Midjourney. Keep "hand behind head" and "gradient sunglasses" explicit so the pose and accessories come out right. 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.
