Ultra-realistic smartphone travel portrait of a young man sitting casually on a stone railing in the Paris streets during late afternoon. He has messy dark brown textured hair with natural volume, fair skin, a slim face, and soft facial features. He slightly tilts his head while looking toward the camera with a calm expression. He is wearing an oversized sky-blue knitted sweater covered with large white cloud patterns, loose cream-colored cargo trousers, and a thin silver necklace. The subject is sitting sideways on a gray stone railing, one hand resting behind him on the stone surface while the other hand rests naturally beside his body. His legs are relaxed and slightly extended. The background features elegant cream-colored Parisian buildings with decorative balconies, classic European architecture, large windows, street lamps, and trees along the road. The Eiffel Tower rises in the distance against the skyline.
