Enchanted Lake Flutist and Submerged Piano

Cinematic fantasy illustration of [Undine], a water-nymph flutist standing waist-deep in a dark enchanted German forest lake at twilight. She wears a flowing, translucent [blue-green] gown that merges with swirling water like silk, with wet shimmering fabric, delicate beaded sleeves, long wavy brown hair woven with tiny blue flowers, and an intentionally obscured, featureless face covered by a soft neutral square blur. She holds a silver concert flute horizontally to her lips. Behind her rests a glossy black grand piano half-submerged in the lake with its lid open, reflecting moonlit teal highlights as water cascades over its strings and rim. In the foreground, an ornate silver dagger with a jeweled gold-and-turquoise hilt lies partly submerged in the water. Two golden fish swim on the right, surrounded by six white water lilies with yellow centers and dark green lily pads. Magical circular currents swirl around the flutist and piano, alive with glowing musical-note trails, sparkling golden motes, and turquoise ripples. Tall shadowy evergreen trees, mossy trunks, mist, and shafts of cool twilight light frame the lake. Painterly realism, romantic and tragic mood inspired by Carl Reinecke's [Undine Sonata], dramatic teal-and-gold color grading, volumetric lighting, crisp water splashes, wide composition, no text, no watermark.
