Transform the uploaded portrait into a realistic emoji mosaic artwork. Recreate the original person's face, hairstyle, pose, expression, body shape, clothing, and composition using hundreds of tiny colorful emojis as mosaic tiles. Each emoji should be clearly recognizable up close, while the full image should still look like the original portrait from a distance. Preserve the subject's identity, facial proportions, skin tone, lighting direction, and background structure. Use emojis with natural color matching to form shadows, highlights, skin texture, hair texture, eyes, lips, clothes, and background details. High-resolution digital artwork, clean composition, sharp details, playful but premium social media style. Do not change the person's face, gender, age, expression, hairstyle, outfit, or pose. Do not create a cartoon face. Do not blur the emojis. Do not use random oversized emojis. Do not distort the portrait.
