An awe-inspiring, surreal nature spectacle. A photo of a colossal, iridescent crystalline waterfall cascading from a crack in the sky, plunging into an ancient, bioluminescent jungle canyon. High definition, masterpiece, wide shot, cinematic lighting. In detail: The 'water' is actually a flowing river of glowing, liquid light and fractal crystals, shimmering in shades of deep sapphire, amethyst, emerald, and gold. The air is filled with glowing dust and mist. Below, the canyon is filled with giant, ancient trees whose leaves and bark softly glow with soft, ethereal cyan and magenta patterns. Massive, glowing fungi grow on the rock faces. In the extreme foreground, to provide scale, a tiny, lone human figure with a backpack stands on a mossy, mist-covered outcrop, their posture one of pure astonishment, looking up. The sky is dark and stormy, illuminated only by the light of the spectacular cosmic waterfall. Technical specs: Ultra-detailed, 8k, Unreal Engine 5 render style, ray tracing, volumetric fog, dramatic chiaroscuro, high dynamic range, stunning, unexpected, hyperrealistic.
