Preserve the original scene, composition, perspective, buildings, streets, objects, lighting, shadows, materials, and photographic textures exactly. Change only the characters into minimalist black-and-white hand-drawn stickers, keeping their poses, actions, proportions, clothing outlines, number, and positions unchanged. Use rough single-line illustrations with only pure black and white no gray, color, or gradients with clean white sticker borders. Create a realistic high-resolution photo background contrasted with flat 2D sketch characters, in a minimalist graffiti/INS editorial collage style. Sharp, detailed, photorealistic background, 8K look. Aspect ratio: 3:4 / 9:16.
