Replace “man centered in the frame” with “man slightly off-center in the lower foreground” and change “a massive demon made of thick black smoke coils upward behind him” to “a colossal demon fills most of the mirror behind him, its head above the man and clawed hands framing his shoulders.” Keep “portrait-full-body” if you want both figures readable, or use “medium full-body portrait” to give the demon more image area.

Replace “faint embers glowing orange-red” and “eyes burn with a dim molten glow” with “frozen blue sparks drifting through the smoke” and “eyes glowing with an icy electric-blue light.” Change “cool-toned, high-contrast lighting” to “severe blue-white overhead lighting with deep black shadows” to remove the warm accents and make the boutique feel more hostile.

Keep “young man taking a mirror selfie,” “centered composition,” and “realistic mirror reflections” fixed, then swap only the setting and entity phrases: use “an abandoned subway station with tiled walls” plus “a pale ghost made of trailing mist,” or “a rain-streaked rooftop at night” plus “a winged creature formed from black feathers.” Preserve “photorealistic dark fantasy” and “cinematic realism” so the variations retain the same visual language.
