Fantasy castle floating island inside crystal sphere

Digital painting of a surreal fantasy landscape featuring a massive floating island encased within a transparent crystal sphere resembling Earth from space. 

Subject: A majestic ancient castle complex with towering spires and gothic architecture built upon the summit of a rugged, moss-covered rock plateau perched on an immense floating landmass; large solitary trees dot the landscape atop the cliffs. 

Environment: The entire island is enclosed inside a giant glass sphere that reflects clouds and distant landscapes; waterfalls cascade down from the underside of the cliff into misty depths below, surrounded by jagged mountain peaks shrouded in low-hanging fog. 

Objects: A flock of birds soars gracefully across the sky above the crystal dome; small structures with pointed roofs line the base of the floating island's perimeter near a winding road or path at ground level. 

Lighting: Soft diffused daylight filters through the clear sphere, casting gentle highlights on stone towers and green foliage while creating subtle internal reflections within the glass boundary that enhance depth and realism. 

Camera: Wide-angle perspective capturing both the grand scale of the floating world inside the globe and its dramatic placement against a vast atmospheric backdrop; composition emphasizes verticality with falling waterfalls leading downward into shadowed voids below. 

Style Details: Dreamlike digital fantasy art style blending hyper-realistic textures on stone, foliage, and glass surfaces with imaginative surrealism evoking wonder and ethereal beauty reminiscent of concept illustrations for epic high-fantasy worlds.
