Dark Shadow

Transform this mirror selfie into a dark, cinematic fantasy scene. Keep the person exactly the same same face, pose, outfit, lighting, and background.
Add a shadowy, smoke-like demonic entity emerging from behind the person's back. The entity should be made of swirling black smoke, semi-transparent, with glowing red eyes.
The smoke wraps around the body and flows down to the floor naturally, blending with the environment.
Maintain realistic shadows, reflections, and depth so the creature feels part of the scene. Dark, moody atmosphere, high contrast, cinematic lighting, ultra-realistic, 4K quality.
No change to facial features, clothing, or camera angle.
