Prompt: Design a digital composition featuring the kangaroo's pedal emitting whimsical retro-pop dreams against an extra beautiful abstract desert scene. Incorporate 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, adding an enigmatic touch to the retro-pop ballet. Integrate this spectral creature with the pointillist spiral vortextuals, dadaist helixical diversions, fauvist spherometric projection, and art brut touches, creating a visually captivating and whimsical dreamscape.
