Change only the carpet. Replace the current bright red carpet with an antique Persian carpet in a very dark wine-red tone, almost black, with elegant, subdued patterns and low saturation. The carpet should feel aged, luxurious, and naturally blend into the dark gothic atmosphere without drawing attention. Keep the blue rose petals on top of the carpet exactly as they are. Do not change anything else. Preserve the character, pose, facial expression, clothing, throne, upholstery, wall pattern, candleholders, candles, lighting, shadows, smoke, blue roses, composition, perspective, colors, textures, and every other detail exactly as in the original image.
