Elegant Three-Diamond Birthday Poster

Ratio 4:5, ultra‑realistic premium birthday poster composed of three diamond‑shaped sections with the subject (use the uploaded reference face unchanged, preserving natural appearance). Central portrait in full colour shows the subject wearing a sage‑green linen shirt, cream trousers, and white sneakers, holding a fresh green leaf, gaze directed downward, genuine smile and relaxed expression. Top diamond contains a close‑up of the subject with eyes softly closed, leaf near the face, smiling naturally. Additional diamond frames present two appealing poses: one figure standing confidently while adjusting sleeves, another leaning casually against a tree, both smiling. Background features a clean white‑to‑light‑grey gradient with soft green smoke, nature‑inspired aesthetic, realistic depth, gentle environmental shadows, and a minimalist luxury feel. Atmospheric details include two birds flying in the sky, drifting green leaves, nature particles, subtle butterflies, glowing particles, light pollen, and soft lens flare. Lighting is bright creamy daylight combined with soft beauty lighting, realistic HDR contrast, and glossy highlights on the medium‑smaller side diamond frames. Camera style: professional DSLR portrait photography, 85mm portrait lens, editorial birthday‑poster composition, shallow depth‑of‑field, luxury collage layout, strong subject separation, balanced geometric framing. Realistic green smoke clouds flow around the diamond frames, adding a subtle dynamic element.
