Rainveil Travertine Fern Cascade

Create exactly one high-resolution portrait-oriented commercial Nature scene in a 2:3 composition at approximately 1024x1536 pixels. Depict Rainveil Travertine Fern Cascade, a secluded rain-fed freshwater spring descending through a compact series of naturally formed pale cream travertine terraces during a gentle overcast morning shower. Make the flowing mineral cascade the unmistakable natural centerpiece, with clear shallow water spilling softly over rounded calcite lips into several translucent turquoise-gray pools. Surround the terraces with delicate native ferns, damp emerald moss, small liverwort patches, silver-green grasses, scattered dark wet pebbles, weathered limestone fragments, and a few slender woodland stems emerging naturally from the slope. Show subtle mineral deposits, irregular stone edges, tiny rivulets, realistic water transparency, fine ripples, wet surfaces, and occasional suspended droplets without exaggerating the scale. Frame the scene from an eye-level 50mm perspective along the lower edge of the spring, allowing the cascade to rise vertically through the portrait composition toward softly misted vegetation in the background. Use diffused cool overcast daylight with restrained warm cream highlights in the travertine, muted green vegetation, gentle rain haze, realistic botanical detail, natural depth, and quiet commercial editorial polish. Keep the ecosystem pristine, plausible, uncrowded, and free of people, buildings, roads, artificial objects, signage, readable text, logos, branding, numbers, or symbols.
