Create a serene image of a city park blanketed in fog, capturing the tranquil atmosphere of nature within an urban environment. The photograph should feature winding pathways lined with trees, their branches heavy with mist, creating a sense of enclosure and calm. Use natural light filtering through the fog to illuminate patches of grass and flowers, enhancing the vibrant colors against the muted backdrop. Incorporate park benches and lampposts, their details softened by the fog, inviting viewers to imagine themselves in this peaceful setting. The composition should lead the viewer's eye along the path, drawing them deeper into the foggy scene. Keywords: "tranquil park," "urban nature," "soft natural light," "mystical atmosphere."
