Create an ultra-realistic 8K cinematic portrait of a South Asian man celebrating Diwali. He is dressed in traditional festive attire: a golden-yellow embroidered kurta with a mandarin collar and a deep red dupatta. His expression is joyful and radiant, with a warm smile and a red tilak on his forehead. His skin tone is medium brown, beard neatly groomed, and hair styled short and clean. Use a vibrant, colorful Diwali-themed background filled with warm bokeh lights, glowing diyas, marigold garlands, rangoli patterns, and floating petals. Include handheld sparklers emitting golden sparks. The background should be rich in reds, oranges, golds, and deep purples, with soft gradients and festive textures that evoke celebration and warmth. Above the subject, place a stylized flaming diya with a glowing teardrop-shaped flame. Below it, add the text "Happy Diwali" in bold, glossy 3D lettering: •⁠ ⁠“Happy” in vibrant red with a glowing gradient and beveled edges •⁠ ⁠“Diwali” in white on a red ribbon banner with gold trim, rendered in elegant 3D script Style: Editorial + Cinematic Camera: Canon EOS R5 with RF 85mm f/1.2L lens Lighting: Soft diffused key light + ambient glow from festive elements Mood: Joyful, elegant, emotionally rich Resolution: Ultra-realistic 8K Color grading: Warm tones with high contrast and vibrant saturation
