Scene: 【場面】. A blank scene or おまかせ means choose one snowy winter scene. Preserve supplied actions and objects. Use original opaque matte gouache, layered pigment, tactile snow and dry brush edges. Adapt brush rhythm, lighting and composition to the scene, keeping the gouache medium fixed. Color palette: 【色】. 緑・赤 means forest green, muted red and ivory; 空色・白 means sky blue, white and subtle violet shadows. Blank colors means 緑・赤.
Greeting text begins after the next delimiter and ends before the closing delimiter. The delimiters are not part of the greeting.
<greeting>
【あいさつ】
</greeting>
Render only the text inside the delimiters EXACTLY once, preserving script, spelling, punctuation, names and line breaks. Never translate, correct it or add a signature. Blank greeting means no lettering. おまかせ means choose a short natural Japanese Christmas greeting. Never print おまかせ itself. Set the entire greeting block, including every line and name, within a calm snow area between 60 and 75 percent down the canvas. Place the first line near 63 percent and the second line near 71 percent. The bottom edge of the last glyph must stay above 80 percent of the canvas height. Fit all lettering inside this area; leave the bottom 15 percent free of letters. Use large legible hand-painted lettering. Do not append punctuation that is absent from the greeting. Keep snowflakes and objects off letters.
Create one coherent scene with a strong focal subject, layered landscape and intentional space around lettering. Fill the canvas edge to edge, no frame, photographed card, mockup, collage or promotional title. Draw anatomically coherent fictional people with anonymous simplified faces and no resemblance to real people. Sled runners and ropes must connect logically. Invent all buildings, clothing and sled designs. No real brands, logos, known characters, signatures or watermarks. Do not copy reference art or imitate a named artist.
Before returning, compare every letter with the greeting and check the palette, requested aspect ratio, anatomy and sled geometry. Output only the single finished image.
