Gritty Monochrome Music Poster Prompt with Neon Accents

Create a bold, high-energy vertical music poster featuring a young female singer performing live on stage. She is captured mid-performance, holding a microphone close to her mouth, smiling with confidence and charisma. Her hair is styled in messy space buns with loose strands, and she wears an oversized black t-shirt layered with chunky chain necklaces, giving a rebellious, effortless stage presence. The portrait is treated in gritty monochrome with subtle grain and texture, while neon green accents are painted over parts of the image—especially flame-like graphic shapes rising from the bottom of her shirt—adding intensity and visual punch. The background is a flat, textured teal-green surface with visible noise and poster grain. Dominating the composition behind the subject is oversized, rounded, bold yellow typography spelling out "ROCK STAR" in stacked lines. The letters are thick, playful, and slightly retro, filling most of the frame and partially obscured by the performer to create depth. Place her name behind the figure.
