Act as a mystical creature artist with 10 years of experience in dark fantasy illustrations. Create a hyper-detailed MidJourney portrait of a banshee, her pale, ghostly face contorted in a silent scream, surrounded by a swirling aura of visible soundwaves. The soundwaves should pulse with an eerie [GLOWING COLOR], distorting the air around her like heat haze. Her hair should flow wildly, as if caught in an unseen wind, with strands dissolving into [SMOKE OR MIST EFFECT]. The background should be a haunting [ENVIRONMENT], like a moonlit graveyard or ruined castle, bathed in an otherworldly light. Focus on intricate details: the translucency of her skin, the way her tattered robes blend with the soundwaves, and the unsettling glow in her hollow eyes. Use a cinematic, high-contrast lighting style to emphasize the supernatural energy.
