Retouch only the background. Do not change Sebastian, Ciel, the dining table, the dinner plate, the silverware, the blue roses, the tablecloth, the composition, the camera angle, the character proportions, the poses, the facial expressions, the lighting on the characters, or any other existing elements.
Replace only the background with a luxurious Victorian gothic dining room. Add a large dark window behind Sebastian with faint moonlight filtering through it, partially veiled by sheer curtains. Surround the window with elegant antique gold picture frames and subtle classical wall moldings. Use deep navy-blue, charcoal, and black tones to create a refined aristocratic atmosphere.
Keep the background softly blurred with gentle atmospheric haze to create depth while ensuring Sebastian remains the dominant focal point. Blend the cool blue moonlight naturally with the existing warm candlelight so the overall mood matches the original illustration.
Do not add chandeliers, stained glass, extra furniture, additional decorations, or any new objects on the table.
Keep absolutely everything else exactly the same. Change the background only.
