Affiche Collage Photo d'Anniversaire

A photo collage birthday poster set against a [teal background] with torn paper top and bottom edges. The collage features four white-framed, photorealistic portraits of the woman from the reference photo, smiling with long dark hair and wearing a [bright orange turtleneck], softly illuminated by natural light. Each portrait shows a different playful pose. The layout is asymmetrical: two vertical frames at the top, one horizontal frame in the middle, and one vertical frame at the bottom left. In the bottom right, a [dark blue] pinned rectangular sign displays the text "[Happy Birthday]" in elegant white cursive script. Scattered [bright orange gerbera daisies] accent the frames and margins, creating a cheerful, celebratory composition.
