Create ONE premium stylized 3D Christmas character portrait. Default aspect ratio: 4:5. Use the selected aspect ratio if supplied. One unmistakably cartoon-like plump 3D character, oversized head, large expressive eyes, tiny simplified nose, smooth sculpted cheeks, small rounded shoulders, toy-like proportions, bust portrait, full hat visible near the top and knit-clad torso reaching the bottom; warm solid background fills all edges. No panels, border, pedestal or packaging.
PHOTO reference: "【写真】". This is an attachment description, never printed. Use the actual attached photo as the sole identity reference. Preserve recognizable facial geometry, eye spacing, eyebrows, nose and mouth proportions, skin tone, approximate age, hair color and part, freckles and moles. Preserve eyeglass frame shape and color when present; do not add glasses when absent. Stylize as a rounded 3D character without replacing the person with a generic face. If several people appear, use only the most prominent foreground adult.
PHOTO RULE: If no photo is attached, do not ask for one; invent one original adult with distinctive features, unrelated to public figures or existing characters.
OUTFIT: "【服】". Interpret アイボリーのニット・青緑のマフラー as ivory cable-knit sweater with teal wool scarf; 緑のニット・からし色のマフラー as forest-green knit sweater with mustard scarf; プラム色のニット・クリーム色のマフラー as plum knit sweater with cream scarf. Custom input changes clothing colors only. Always retain a red Santa hat with white trim, knit sweater and thick scarf. Empty outfit defaults to ivory knit and teal scarf.
BACKGROUND COLOR: "【背景色】". アプリコット means apricot, 暖かなクリーム色 means warm cream, ローズベージュ means rosy beige. Accept other requested warm colors. Empty background defaults to apricot. Use a single solid color, no scenery.
Art direction: premium dimensional 3D illustration with carefully sculpted cheeks, soft studio lighting, natural eye reflections, tangible knit stitches, softly groomed hair and balanced rich colors. Let the subject's original expression and chosen palette create distinct moods: ivory/teal with apricot feels playful, green/mustard with cream feels cheerful and cozy, plum/cream with rosy beige feels calm and elegant. Strongly simplify skin into smooth sculpted shading without photographic pores. Visibly enlarge the eyes and head while keeping their spacing and the identifying facial features. This must look like a rendered animated character, never a real person wearing Christmas clothes. Keep the same rounded 3D portrait medium throughout; never turn the result into a photograph or flat drawing. Keep shoulders believable; hands outside frame.
No text, letters, numbers, name, captions, logos, signature, watermark, recognizable public figure likeness or existing fictional character. Do not print field values. Produce one finished image in one response.
