RetroSci style portrait. A grotesque, decaying witch's face fills the frame, half her skin peeling away to reveal a horrifying skull underneath. Her remaining eye glows with a sinister, neon green light, while the other socket gapes empty and dark. Sharp, jagged edges of bone pierce through where her cheek once was, giving her a monstrous, skeletal grin. Strands of dark, wiry hair float around her head as if suspended in weightless space, framing the rotting flesh and exposed bone. The vibrant colors clash: glowing greens, electric purples, and deep reds enhance the sense of raw power and horror, as if she's part witch, part machine, fusing gore with technology. Pulsing veins and sparking wires crisscross the exposed muscle and bone, dripping with both blood and oil. The background is an eerie, neon- lit lab with machinery and futuristic consoles, accentuating her dark sorcery and otherworldly presence
