燃え盛る溶岩荒野の上にそびえる巨大な髑髏火山要塞

A colossal 3D volcano sculpted into a grim skull rising from a lava-filled wasteland; the skull’s eye sockets glow molten orange, its jaws drip lava, and a crown of dozens of smaller skulls sits atop the cranium; lava pours from the mouth and throat, forming glowing rivers across cracked basalt ground. Storm-dark skies churn with lightning, ash and smoke; color palette of fiery oranges and reds against midnight blues and grays. Texture-rich, hyper-detailed digital painting with cinematic lighting, dramatic chiaroscuro, wet-reflective lava surfaces, foggy haze, and high-detail bone-like rock. Perspective: centered, low-angle, expansive landscape that conveys scale and menace. Style: dark fantasy / epic horror illustration, ultra-detailed, high dynamic range.
