Underground club style robot AI voice-over ad poster

Create a dark, high‑contrast poster with a moody, underground club aesthetic. The composition features a monochrome portrait of humanoid male robot from the chest up, shot from a slightly low angle for attitude and power. He wears large over‑ear headphones. One hand is raised near her head, the other near his chin, creating a dynamic, expressive pose associated with music immersion. Behind his head is a large flat golden‑yellow circular shape, like a spotlight, creating a strong focal point and visual contrast. The background is deep black with subtle grunge textures, dust, scratches, and poster‑wear imperfections, giving it a raw, printed‑flyer feel. Main headline: "AI VOICE OVER SERVICES". Additional callout text: "Narrate • Engage • Convert". Use 2:3 aspect ratio.
