Ritratto Halloween Haunted Unicorn

Create an original haunted unicorn mascot portrait for a Halloween costume concept. The subject is an adult wearing a wearable, theatrical unicorn mascot costume: soft ivory plush head with a long silver horn, one slightly mismatched button eye, a stitched velvet smile, and a tattered black-and-cream ruff. The costume should look handmade and unsettling but not gory. Preserve the wearer's human jaw and hands so the person remains visibly inside the costume. Dark autumn forest background with shallow fog and a single warm lantern. Photorealistic editorial photography, realistic plush texture, cinematic lighting. No text, no logos, no watermark. Do not copy any film or game character design.
