Città sottomarina surreale dentro di un antico globo di neve gigante

A stunning, surrealist digital art piece of an underwater realm contained within a giant ancient snow globe on the dark ocean floor. Inside the aquatic glass sphere, a futuristic coral city glows with pulsing neon cyan and violet illuminations. Instead of snow, floating bioluminescent plankton particles and elegant translucent giant jellyfishes drift gracefully through the water layers. Beautiful light caustics and water refraction rays beam through the glass panels into the dark deep-sea background. Masterclass lighting symmetry, highly original.
