Ice age selfie image prompt

Amateur iPhone selfie, real photograph, high-ISO grain, slightly soft, dull realistic colors, flat phone-camera dynamic range – looks exactly like a real action selfie snapped on a phone at arm’s length while running. NOT cinematic, NOT painterly, NOT illustrated, NOT rendered. A real prehistoric ice-age man takes a frantic selfie while leading a hunt: [the person from the uploaded reference photo] reimagined as a real caveman, face close and large at arm’s-length selfie angle, wide-eyed comical panic. A few meters behind, a real Smilodon saber-tooth cat with long curved fangs chases him (real fur, matte, not plastic, not CGI). Rough animal-hide clothing. Real ice-age grassland, overcast sky, motion blur. Use the uploaded photo as the highest-priority facial reference. Preserve the person’s exact identity, hairstyle, skin tone, eye color and features. Do not generate a generic face, do not beautify, do not slim. Vertical 4:5. 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.
