Prompt: Develop a digital artwork where the kangaroo's pedal is accompanied by an ethereal waltz against an extra beautiful abstract desert background. Infuse a surrealist portrait of a spectral creature with ghostly flesh and a fissured bone carapace, emerging from an ethereal abyss. The luminous eyes of the creature peer into the void, creating a haunting and enigmatic presence within the waltz. Merge this spectral creature with the pointillist spiral vortextuals, dadaist helixical diversions, and fauvist spherometric projection, crafting a surreal and dynamic composition.
