"Create a festive scene featuring a variety of Bengali pithas and pulis placed on a traditional brass thali. Include a mix of sweet and savory varieties such as "Dhokar Puli," "Patishapta," "Chingri Pitha," and "Kolar Pitha," with details like coconut stuffing, jaggery glaze, and sesame seeds. Add a touch of Bengali folk decor, like colorful rangoli or small diyas in the background, to enhance the warmth and celebration of the scene. The image should evoke the essence of Bengali winter delicacies with vibrant colors and rich textures."
