Create an image of a teenage girl standing confidently in an urban setting, wearing trendy streetwear. The image should feature bold, colorful graffiti walls in the background, with a soft focus to highlight the subject. The girl should have medium-length wavy hair, a vibrant oversized hoodie, and ripped jeans. The lighting should be natural with golden hour tones, casting a warm glow on the girl's face. Use a shallow depth of field (f/2.8) to blur the background slightly, while keeping the focus on her face and clothing details. Apply a subtle HDR effect to enhance textures and color grading for a dynamic and high-contrast look. Add a slight lens flare effect to emphasize the sunlight, creating a vibrant, energetic atmosphere perfect for social media engagement.
