"Create an image of Lord Shiva sitting gracefully on Nandi, his sacred bull

"Create an image of Lord Shiva sitting gracefully on Nandi, his sacred bull. He has a serene expression, with long matted hair, a crescent moon on his head, and a snake coiled around his neck. Lord Shiva is holding a trident in one hand and his other hand is in a blessing gesture. Beside him stands Lord Ganesha, his son, with a joyful expression. Ganesha is holding his modak (sweet) in one hand, with his trunk gently curled. The background is set in a calm, mountainous region with a flowing river, representing the peaceful and divine atmosphere of Kailash."
