Prompt

Create a 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, centered slightly left, with glossy short fur, tall alert ears, long fine whiskers, and pale golden eyes gazing calmly toward the left side of the frame. Around its neck is one antique gold filigree necklace with a central dark oval gemstone pendant and one small dangling teardrop charm. The setting includes exactly 5 prominent background/decor elements: one heavy dark purple velvet curtain with one gold tassel tieback on the left, one gilded picture frame high on the back wall, one ornate carved gold side table on the right, one gold vase holding deep purple flowers, and one dark purple cushion with gold trim at the lower right. Use 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.
