Social Media Post - Autumn Park Bench Portrait

A photorealistic full-body portrait of a beautiful young woman sitting on a dark green park bench in an autumn park with trees and fallen leaves. She has fair skin, striking green eyes, and dark brown hair styled in a messy bun with soft strands falling around her face. She is smiling gently at the camera. She is wearing a pale yellow button-up linen shirt with sleeves rolled up to her elbows, black wide-leg trousers, and black-and-white sneakers. One hand is resting naturally on the bench beside her, and the other hand is placed elegantly on her lap/thigh. Her legs are crossed casually in a relaxed and stylish sitting pose. Keep the exact same face from the reference portrait with no changes to facial features, expression, or makeup. Natural soft daylight lighting, highly detailed, cinematic composition, 9:16 vertical aspect ratio.
