Gritty Monochrome Rock Music Poster

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 charisma and confidence. Her hair is styled in messy space buns with loose strands, wearing an oversized black t-shirt layered with chunky chain necklaces. The portrait is rendered in gritty monochrome with subtle grain and texture, accented with painted neon green graphic shapes, including flame-like motifs rising from the bottom of her shirt. Background is a flat, textured teal-green surface with visible poster noise and grain. Behind the subject, oversized rounded bold yellow typography spells out "[ROCK STAR]" in stacked lines, filling most of the frame and partially obscured by the performer to establish depth.
