Ancient whale gliding through a ruined underwater metropolis

A colossal, ancient whale, its rough skin shimmering with scattered light, soars through an underwater abandoned metropolis of impossible, ruined skyscrapers. The scene evokes epic scale and ethereal beauty, rendered in a painterly digital illustration style with 8k resolution, featuring dynamic lighting and a vivid color gradient, reminiscent of the fantastical works of John Harris and Syd Mead.
