Aristocratic Victorian Gothic Cat Portrait

Photorealistic vertical portrait of one elegant [black] cat sitting upright on an ornate purple-and-gold brocade cushion in a dark Victorian interior. The cat is the single main subject, positioned slightly left of center, with glossy short fur, tall alert ears, long fine whiskers, and pale golden eyes gazing calmly toward the left. Around its neck is an antique gold filigree necklace with a central dark oval gemstone pendant and a small dangling teardrop charm. Background decor includes a heavy dark purple velvet curtain with a gold tassel tieback on the left, a gilded picture frame on the back wall, an ornate carved gold side table on the right, a gold vase holding deep purple flowers, and a dark purple cushion with gold trim at the lower right. Moody low-key lighting, soft natural background blur, shallow depth of field, rich black and plum tones, warm antique gold accents, detailed realistic fur texture, and a luxurious gothic aristocratic atmosphere. No text, no watermark, no extra animals.
