Caricature illustration with scratchy pencil linework, cel shading, grungy retro texture, comic book feel. A female soul vocalist with exaggerated large expressive eyes and a wide-open mouth, gripping a vintage chrome microphone stand. Natural warm caramel skin tone. Floor-length neon orange coat. Busy background bursting with colorful retro disco lights, shimmering glitter balls, glowing Soul-Train inspired stage arches, vivid rainbow light beams, and dense confetti. No photorealism, absolutely no text, no letters, no typography, no watermark, no white areas.
