# Describe the number, name, and appearance characteristics of the characters in the reference image here
[{argument name="Character Appearance" default="A girl wearing a cloak and a girl in a sailor uniform"}]

A watercolor illustration where all the above characters have transformed into cute “snowmen.”

Conversion Rules:
- The bodies of all characters will take the shape of a “snowman without limbs,” consisting of stacked white snowballs.
- The whole body is composed of 2 or 3 snowballs. Taller characters should have 3 segments.
- Eliminate human skin, limbs, and clothing details, making the body out of snow.
- To identify each character, only their characteristic “hats,” “ribbons,” and “image-colored buttons or scarves” should be attached to the snowman.
- The face should use simple snowman parts (black round eyes, orange or round nose).

★ Important Material Rule (Hair Correction):
- [Highest Priority] Hair parts must never be drawn as “human hair” or “wigs.”
- The shape of the hair is maintained, but the material is entirely “pure white snow mass.”
- Completely ignore the original character's hair color (such as black or brown) and express it in the snow's original “solid white (#FFFFFF).”
- Do not draw individual strands of hair; depict it as a “single mass” of compacted snow.
- Eliminate the boundary between the head snowball and the hairstyle part, integrating them like a single large snow sculpture.
- The texture should not be smooth but should have the “roughness” and “unevenness” characteristic of snow.
- The hair shape should be drawn as a “white silhouette” integrated with the snowman's head. The ends of the hair should not be sharp but rounded and plump, like melting snow.

Art Style:
- Analog-feeling watercolor painting.
- White drawing paper texture.
- Outlines are soft, and colors are pale and blurred.
- The background is white or a faint snowy landscape.
