An ombre-colored exquisite surreal 3D rendering, featuring a rectangle-shaped traditional fruitcake placed inside spheres, illuminated by gradient light from within. It combines elements from art nouveau artists such as Alphonse Mucha, Roger Hargreaves, and Paul Klee, creating a sense of three-dimensionality and a fantastical effect. Studio lighting, color correction, and post-processing are used to produce a unique artwork.
