IDENTITY PRESERVATION INSTRUCTION:
Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while transforming them into a festive winter character. Maintain the original facial structure, expression, and identity throughout the transformation.

TRANSFORMATION DESCRIPTION:
Transform the person into either Ded Moroz (Father Frost) or Snegurochka (Snow Maiden) character. For Ded Moroz: apply a long white beard, bushy white eyebrows, traditional red velvet coat with gold embroidery, fur-trimmed hat, and a magical staff. For Snegurochka: apply a traditional blue or white winter dress with silver embroidery, fur-lined hood or wreath with winter flowers, delicate makeup, and a gentle winter aura. The costume should fit naturally on the person's body proportions. Add subtle winter elements like falling snowflakes and soft frosty breath effect.

- Color palette: Rich reds and golds for Ded Moroz, soft blues and whites for Snegurochka, with cool winter tones throughout the background
- Background treatment: Winter forest scene with snow-covered trees, distant village lights, or traditional Russian interior with holiday decorations, slightly blurred to keep focus on the character
