Birthday Poster AI Prompt with Red Grunge Typography

Transform the person in this uploaded photo into a dynamic birthday poster collage featuring four poses of the same person. Keep all faces 100% identical to the uploaded photo — same face structure, skin tone, and features exactly matched, don't change the identity. Arrange the composition with a central full-body figure walking confidently forward, wearing a plain white long-sleeve t-shirt, blue jeans, white sneakers, and a silver watch. Behind and above this central figure, place three chest-up portraits blended into the background: one at the top-center wearing a brown overshirt with black sunglasses looking forward; one on the mid-left looking towards the right wearing a light pink button-down shirt; and one on the mid-right looking towards the left wearing a brown overshirt. Set the scene against a light grey textured grunge background with bold, expressive red paint splatters behind the portraits and swirling white smoke effects blending around the central figure's legs. Add two text elements: first, "HAPPY" at the top-center as a headline in a black, distressed, brush-stroke font; second, "BIRTHDAY" directly below it in a massive, bold, red distressed brush font. Render all text exactly as written — same spelling, same position, same font style and color, with no extra words and no changed letters.
