Banshee Concept Art in a Castle Courtyard

An ethereal banshee hovers through a castle courtyard at dusk in a concept art style. A translucent, ghostly woman in a tattered flowing cloak, hair streaming, with a pale blue-green glow outlining her form. She softly wails, with wisps of wind curling around her. The courtyard features ancient Gothic stone walls with pointed arches, looming gargoyles, ivy crawling over mossy flagstones, and a cracked fountain. Mist swirls on the ground, torches burn dimly, and faded banners hang from the walls. Cinematic lighting, moody chiaroscuro, painterly textures, high-detail fantasy illustration. Color palette dominated by cool blues, greens, and grays with warm amber highlights from torches and moonlight filtering through clouds. The scene feels dramatic, spooky, and majestic, suitable as a fantasy game concept art.
