Instagram-Style Editorial Streetwear Collage

Create a 4:5 modern Instagram-style grid collage featuring the same person as in the uploaded reference image, preserving their facial identity consistently. Use one large central photo surrounded by smaller posts, viewed from a high-angle, top-down perspective. Add subtle social media UI details such as username bars and heart icons, and display the username ${username}.

Dress the person in a red sweatshirt, black cargo pants, white sneakers, and a shoulder bag. Include candid poses: walking, adjusting their hair, looking up, fixing their bag, and holding a coffee. Set the scene on an urban street with textured gray asphalt. Use natural daylight, soft shadows, muted tones with red accents, an ultra-realistic DSLR look, Octane Render, Unreal Engine 5, and a premium editorial fashion style.
