Replace ONLY the background of the photo. Keep the girl in the foreground completely unchanged — do NOT alter her face, facial features, expression, skin, hair, hairstyle, body, pose, or her clothing (grey corduroy jacket over a grey t-shirt with a black heart and "KINHEIK" text). Preserve her exact appearance, lighting on her, and proportions pixel-for-pixel.
Replace the entire background (currently the Yaroslavl railway station square with the yellow clock-tower building, cars, sky and pavement) with the interior of a cozy cattle barn / cowshed (коровник): wooden or metal stalls with several dairy cows (black-and-white Holstein and brown cows) standing and lying in the hay, straw and hay bales on the floor, rustic wooden beams and posts, warm natural light coming through barn windows, soft ambient farm atmosphere. Blend the new background naturally with the girl's existing lighting and edges so the composite looks realistic and seamless.
Keep the original 16:9 aspect ratio and photographic realism.
