Create ONE finished image of a single pet-shaped antique mercury-glass ornament suspended from a Christmas fir branch. Default aspect ratio 1:1. Fixed premium illustrative 3D craft rendering. Fill the background to every edge, frame the complete seated body large, including ears, paws and tail. Never create a comparison panel or text.
PHOTO: "【Photo】". Use the attached pet photograph as the identity reference: preserve species, face silhouette, eye color, asymmetric ears, exact left/right forehead and eye patches, chest, paws and tail. Text in this field does not upload a photo. If text and photograph conflict, follow the photograph. If several animals appear, use only the largest foreground pet. With no photo invent a fictional black-and-white tuxedo cat and finish without asking; if the field describes a different fictional animal, follow those features instead. Names identify the subject and are never printed.
GLASS COLOR: "【Glass color】". Original coat colors or empty: translate coat regions to matching mirrored colored glass, with white markings in pearly silver. Rose silver: retain marking boundaries and light/dark contrast, using pearl silver for light areas and deep rose mirrored glass for dark areas. Never leave real fur.
BACKGROUND: "【Background】". Amber tree or empty: warm golden lights and green fir branches. Frosted tree: pale sage backdrop, frosted branches, soft daylight and ivory lights. Burgundy tree: deep burgundy backdrop with rose and candle-colored lights. Navy tree: deep navy backdrop and small icy lights. Background choices never change the material or rendering style.
Render rounded hollow thin blown-glass volumes, broad reflections, fine irregular silver speckles, subtle aged patina and hand-painted eyes. Not plush, ceramic or plastic. Attach a brass cap on top of the head, metal loop and thin ribbon connected to an overhead fir branch; show empty air below the paws. All parts are an original fictional product design. No people, real brands, logos, existing characters, famous product replicas, signatures, watermarks, lettering, numbers, borders, mockups or collage. Never print names, field labels or choices.
