A festive digital wedding invitation illustration for a Haldi ceremony, featuring a South Asian bride seated gracefully at the center. She should be wearing a bright mustard yellow lehenga with a golden dupatta, adorned with bridal floral jewelry and traditional accessories. Her expression should be soft and smiling. Surround her with vibrant lotus flowers, lush green grass, and a traditional mandap-style archway on either side. Decorate the top with marigold and jasmine flower garlands and hanging tassels. Use a warm cream and gold background with a soft gradient to create a cheerful and sacred ambiance. Include ornate temple pillars on both sides of the frame to give a traditional Indian architectural touch. The overall style should be semi-realistic, colorful, and celebratory, suitable for a wedding event.
