Demon Bodybuilder i

Use the reference photo. The left half of the face is the exact real person: same facial structure, skin tone, hair, eye and expression, unchanged. The right half of the face is a realistic demon, split cleanly down the center line of the face. Demon half: dark red-brown skin with cracked, lava-like glowing veins, a curved horn growing from the forehead and temple, a glowing amber-orange eye with a slit pupil, sharp cheekbone ridges, and slightly pointed ear. Skin texture is detailed and realistic, like high-end cinematic makeup and VFX, not a cartoon. Keep the body, physique, proportions and pose from the reference photo. Natural muscle definition, no exaggerated size. The demon transformation continues subtly along the right shoulder and arm, with a few faint glowing cracks in the skin. Setting: pure black background, dark gym atmosphere, with faint silhouettes of gym equipment barely visible in the shadows. The person is in full natural color. Lighting: cool white key light on the human side, warm orange-red firelight glow on the demon side, strong rim light on the shoulders, deep shadows, rich blacks. Faint embers and smoke drifting in the air. Shot on a full-frame camera with an 85mm lens at f/2, sharp on the face, photorealistic, cinematic, dramatic movie-poster style, high detail, subtle film grain. - **Use your photo as the reference** with the strength around 60–70%. Too high and the demon half won't appear. Too low and your face may drift. - **If it turns fully demon,** add "the left half of the face is completely untouched and looks like a normal human" to the prompt. - **Swap the sides** if you'd rather have the demon on the left. The model can mix up left and right, so try both. - **For a subtler look,** change the demon half to "burning ember eye, small horn, faint glowing cracks in the skin" and remove the red skin. - **Your photo has your head tilted down,** so the split may look uneven. A straight-on or slightly angled photo will give a cleaner center line. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
