Moonlit Banshee on the Desolate Beach

Hyper-realistic, cinematic depiction of a banshee on a moonlit beach. A pale, translucent female spirit stands at the water line, her long hair whipped by the wind, wearing a ragged, diaphanous shroud that glows faintly. She is wailing, mouth open, outlined by a cold blue-green halo. Wet sand reflects the silver moon while foamy waves crash softly behind her. Driftwood, seaweed, and scattered shells dot the shore. A light mist rises from the surf; stormy clouds part to reveal a sliver of moonlight; distant rocks silhouette on the horizon. Ultra-detailed, 8K realism with volumetric lighting and filmic grain, cool palette of blues, silvers, and ghostly whites; shallow depth of field centered on the banshee with the background softly blurred.
