일본 특급 열차 여고생 셀카

A realistic vertical smartphone selfie photo inside a Japanese limited express train carriage. Two cheerful Japanese high school girls sit side by side in green-gray upholstered train seats with white antimacassar headrest covers, viewed from a high wide-angle front-facing camera held by the girl on the left, whose extended arm is visible in the lower-left foreground. Both girls have straight black hair, youthful faces, natural skin texture, rectangular eyeglasses, and warm smiles. The girl on the left has shoulder-length hair with side bangs, wearing a white short-sleeve school uniform shirt, an ivory sleeveless sweater vest, a dark navy pleated skirt, navy knee socks, white sneakers, and a dark striped ribbon bow. The girl on the right has long hair tied back with side bangs, wearing a white short-sleeve school uniform shirt, a pale pink sleeveless sweater vest, a navy pleated skirt, navy socks, white sneakers, and a red striped ribbon bow, posing with a peace sign near her face with her right hand. The train interior includes armrests, a window on the right reflecting a dark exterior, muted beige flooring, and soft overhead lighting. Large text in the top-left corner reads "[GPT]" in bold rounded magenta lettering with a thick white outline. A faint semi-transparent watermark across the lower center reads "[©CottonAIImageLabo]". Candid photorealistic snapshot, subtle wide-angle lens distortion, clean composition, no extra passengers.
