Giant head tiny body

Create a highly realistic funny oversized-head portrait of a man standing in a beautiful European-style narrow street. Make the man's head and face extremely large compared to his small body, creating a realistic but humorous giant-head effect. Keep the face highly detailed and natural, with realistic skin texture, short black hair, thick beard and mustache, and black sunglasses with a subtle red detail on the frame. He is wearing a brown leather jacket over a black shirt, loose light-blue jeans, and black shoes. His body should look naturally small compared with the oversized head. Pose him standing with legs apart and both hands slightly raised in a confused/funny gesture. Background: elegant European old-town street with warm beige buildings, balconies, windows, stone pavement, parked scooters and motorcycles. Natural daytime sunlight, realistic shadows, cinematic DSLR photography, shallow depth of field, ultra-detailed textures, photorealistic lighting, realistic proportions except for the intentional oversized-head effect. Make the final image look like a real photograph, not cartoon or illustration. No text, no watermark, no logo. Use my uploaded photo as the strict face reference and preserve my exact facial identity. 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.
