Portail cosmique surréaliste avec sphère flottante et clé

A masterpiece: an ultra-hyperrealistic, abstract cosmic landscape in 16K UHD, captured as a conceptual digital sculpture with a Hasselblad X2D 100C, 120mm lens, ISO 100, 1/60 s, f/11, and full focus stacking. A surreal, swirling geological structure forms a circular portal of creamy textures and eroded mineral formations, leading to a floating, planet-like sphere at the center. Warm, amber clouds mingle with turquoise streams that cascade like alien waterfalls. The composition follows the golden spiral, drawing the eye to the central sphere. In the foreground lies a mysterious, wondrously crafted gold-copper key, the key to knowledge. Volumetric lighting creates an ethereal depth and a cinematic atmosphere, inspired by Zdzisław Beksiński, Android Jones, and futuristic conceptual art. Ultra-detailed textures, micro-grained surfaces, and photorealistic global illumination. The final result is optimized for large-format fine art prints.
