A highly detailed, dramatic, and atmospheric digital painting suitable for a professional audiobook cover. The focus is on the Trevi Fountain in Rome at dusk, bathed in the dramatic light of sunset. Cherubic sculptures are carved with intense detail, water cascades with powerful realism, and the marble appears almost alive. Subtle rays of warm, golden light pierce through gathering, deep indigo clouds. The overall mood is one of mystery, grandeur, and a touch of melancholic beauty. The composition is a close-up perspective, emphasizing the intricate details of the fountain and creating a sense of depth and immersion. The color palette is rich and dramatic, dominated by deep blues, purples, and ochres, with highlights of gold and white on the water and marble. The style is a photorealistic interpretation of Baroque art, with a painterly quality. Square 1024x1024 format, no text, no logos.
