Stadium Anthem Reel Poster Prompt for Boys

Create a photorealistic vertical 9:16 anthem poster of the boy from the reference photo, keep his face same as reference with identical features and confident calm expression, not CGI, not illustration. He stands in a strong static pose in a stadium tunnel with dramatic floodlights behind, wearing a black oversized t-shirt and chain, arms crossed loosely with both hands fully visible showing five natural fingers. Leave the top third of the frame as clean empty smoky space for anthem title text, place the subject in the lower two thirds with glowing light rays behind. Capture with a Sony A7IV and 40mm f/1.8 lens look, high contrast cinematic grade, sharp focus on the face, dramatic rim light on shoulders, detailed fabric texture, realistic shadows and bold poster punch. Preserve his facial identity exactly without face change or over editing, natural body proportions, no extra fingers, no blurred hands, no distorted jewelry, no warped lights. Finish with gritty film grain for a real stadium anthem poster feel.
