Glowing Mushroom Skull Fantasy Diorama

Surreal hyper-detailed dark fantasy diorama sculpture on matte black museum podium: monumental bioluminescent mushroom with deep blue organic hat, fine dot and micro-structures, glowing inside in gold, orange and red; translucent slats with realistic subsurface scattering. Below is an anatomically correct, slightly patinated skull, eyes and mouth warmly lit from the inside. A swinging golden staircase leads from the skull into the mushroom, moderately, slightly aged gold with fine scratches. Moss-protected island base with miniature plants, flowers and fungi. Dark studio background with fog, cinematic light, strong warm-cold contrasts, centered composition, slightly increased perspective. High-end 3D, Octane/Unreal look, photorealistic materials, 8K, clean, mystical.
