Create a cinematic, ultra-realistic 15-second Diwali celebration video using my uploaded selfie, diya photograph, and voice reference.

**Video format:** Vertical 9:16, 720p, cinematic lighting, realistic visuals.

**Scene 1 (0–3 seconds):** Begin with an extreme close-up of a glowing diya. The flame flickers naturally. Slowly zoom out to reveal a beautiful, colorful Indian rangoli surrounded by marigold flowers and dozens of illuminated diyas.

**Scene 2 (3–7 seconds):** Transition into a beautifully decorated Indian courtyard at night. Golden fairy lights sparkle, colorful phuljharis illuminate the background, and the camera moves smoothly through the festive atmosphere.

**Scene 3 (7–12 seconds):** Show me standing in the courtyard wearing an elegant traditional kurta. Preserve my exact facial appearance from the uploaded selfie. I look directly at the camera, smile naturally, and say in a warm Indian accent:
