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.
