Mixed-Reality Street Portrait with a Cartoon Twin

Transform the uploaded image into an ultra-high-resolution mixed-reality street portrait. Preserve the face and identity of the young woman in the reference image. Show her sitting on urban steps beside her cartoon-illustrated twin. Set the scene outdoors against a textured concrete wall, with a tall window reflecting trees and soft indoor light. Include worn steps with chipped paint for added realism.

Dress the woman in relaxed Y2K-inspired streetwear: an oversized cropped hoodie, baggy dark jeans, chunky sneakers, and a beanie. Pose her casually with one knee raised, looking slightly away with a calm, confident expression. Her illustrated counterpart should match her pose, outfit, and proportions exactly, rendered in a bold, flat graphic style with thick black outlines and vibrant colors. Align the cartoon arm with the real woman's arm to create a playful interaction.

Use natural daylight to light both figures evenly. Blend realistic textures with clean cartoon shading for a cool, nostalgic, creative mixed-media look.
