Professional book cover art, cinematic thriller style. A massive, jagged, deep-blue iceberg floating in dark, frigid arctic waters under a twilight sky with soft aurora borealis ribbons. In the side of the iceberg, a partially visible, rusted, and frozen metal hull of a luxury 1950s yacht is embedded in the ice. Hyper-realistic texture of melting ice and dark, turbulent, icy waves. Deep navy, teal, and cold white color palette with sharp, dramatic lighting. Moody, mysterious, and cold atmosphere. High-end digital painting, 8k resolution, cinematic composition, square 1024x1024, no text, no letters, no words, no signatures.
