Create a vibrant Onam festival poster that highlights the cultural essence of Ke

Create a vibrant Onam festival poster that highlights the cultural essence of Kerala. The poster should prominently feature King Mahabali, depicted as a kind and majestic figure wearing traditional attire with a golden crown and elaborate jewelry. Surround him with an intricate Athapookalam (floral rangoli) at his feet, made of vivid, colorful flowers arranged in a beautiful pattern. In the background, include a traditional Kerala snake boat (Chundan Vallam), elegantly gliding through the serene backwaters, with rowers in traditional white attire. The overall color scheme should be festive, with bright, warm colors symbolizing the joy and prosperity of Onam."
