Transform the uploaded couch photo into an elegant Halloween portrait of the same tuxedo cat. Preserve the cat’s exact identity, black-and-white face mask, amber eyes, coat markings, loaf pose, expression and anatomy. Move the cat to a dark velvet chair, add only a tiny plain burnt-orange bow collar, tasteful miniature pumpkins, warm candle-like bokeh and a moonlit blue rim light. Keep the full cat visible and the scene whimsical but photorealistic rather than scary. Do not add a witch hat, human clothing, extra limbs, change markings, use copyrighted character styling or add text.
