Generate this image now. Draw it directly; do not explain or ask questions.
Output size 1080x1350 pixels, 4:5 portrait, Instagram standard.
Create ONE full-bleed Christmas story illustration, default portrait 4:5. Show one pet in a snowy environment with readable action, not a face-only portrait. Keep the face large enough to recognize and the scene rich to every edge. No collage, no mockup, no border.
PHOTO: "【Photo】". Use the attached photo as identity reference, preserving species, eye color, muzzle, ear shape, fur color, white areas, exact LEFT/RIGHT asymmetric patches, tail and proportions while translating to the selected style. Photo field text describes features; it is not an image file. With no attachment, invent one fictional friendly dog and complete the image without asking.
NAME: "【Name】". Name alone identifies the pet; do not print it. Only if this field contains a slash followed by "Caption:" print the exact following caption once, small but legible near the lower center with a safe inset. Empty field or no caption marker means absolutely no text. Never invent a caption or repeat the name separately. Output lettering in the selected caption language.
SCENE: "【Scene】". Interpret only the selected choice:
- Pulling a sleigh: pet walking happily in three-quarter view on snow, four natural legs; a loose chest harness connects by two visible unobstructed traces to a small wooden gift sleigh BEHIND it. Show complete runners, natural connections, no strain or neck pulling.
- Riding a sleigh: pet seated safely INSIDE a small wooden sleigh with wrapped presents; paws rest naturally at the front, runners and snow tracks visible.
- Gift pile: pet sitting on snow among three differently wrapped gift boxes, tail visible, paws grounded, snowy pines and lights behind it.
Empty scene means Riding a sleigh.
STYLE: "【Style】". Interpret only the selected choice:
- Storybook watercolor: storybook watercolor, visible pigment washes, delicate pencil contours, pale peach dawn and icy blue snow.
- Cute 3D: clearly stylized cute 3D animation, large head and petite rounded body, sculpted fur clumps rather than photographic hair, matte clay and felt materials, lavender twilight and warm amber lights. Not photorealistic.
- Vintage card: vintage Christmas gouache illustration, textured print finish, muted cranberry and forest green, snowy pine silhouettes and warm cabin lights. No aged paper border.
Empty style means Vintage card.
The pet wears a soft felt antler HEADBAND and a small red costume nose; do not turn it into a reindeer. Preserve visible eyes and recognizable muzzle. Use species-appropriate anatomy. This is a fictional playful illustration. No humans, celebrity likenesses, brands, logos, existing characters, signatures, watermarks or unrequested numbers. All props and gift wraps are original fictional designs. Never print field labels or choice names. If no caption was requested, print no text at all.
