Oversized Head Travel Portrait

Edit the input single-person travel photo into "OVERSIZED HEAD TRAVEL PORTRAIT｜Exaggerated Big-Head Travel Portrait." Retain the original photo's authentic environment, viewing angle, lighting, depth of field, and person's identity; only alter the person's proportions: enlarge the person's head, face, and hairstyle overall by about 1.5 to 2 times, shrink the body, limbs, and clothing to about 35% to 60% of the original proportions, creating a pronounced big-head small-body effect. Preserve realistic skin texture, facial features, expression, hair strands, hat, earrings, and clothing material, keeping the gaze, movement direction, and pose unchanged; naturally reconstruct the head-shoulder connection, collar, arms, sitting posture, ground contact, and shadows, prohibiting neck breaks, floating elements, deformed hands and feet, duplicate figures, or extra limbs. The background must remain the original photo's plants, roads, buildings, or travel environment, without replacing with color blocks, solid-color backgrounds, or new landmarks. Overall, maintain a realistic photography texture, with only subtle soft lifestyle photography color grading; the effect's core must come solely from the head-to-body proportion changes, not from color swaps, comic filters, halftone dots, or plastic 3D styles. Default to no added text, logos, watermarks, AI badges, original image badges, stickers, or fake Chinese text. 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.
