Birthday Poster

Create a fresh and elegant birthday poster with sky blue and teal watercolor paint splashes mixed with soft cloud textures and glowing butterflies. Use one large smiling close-up portrait and one full-body pose of a stylish young woman wearing a blue denim jacket, white crop top, jeans, and sneakers. Add elegant handwritten birthday text with soft lighting, dreamy Instagram aesthetics, watercolor texture blending, and modern youthful vibes.
