Snow Background

Replace the background of this photo with a serene [snowy pine forest under soft falling snow], so the whole image looks like one real photograph taken on location, not a cutout placed on a backdrop. Keep the person's face, pose, and outfit unchanged, but relight them to match the scene, with cool soft winter daylight and a gentle ambient glow spilling naturally onto their skin and hair. Blend the winter scene behind them with realistic depth, gentle drifting snowflakes, frosted branches, and a softly blurred backdrop, add natural contact shadows, and match the color grade and grain across the whole frame. Keep the edges soft and natural around the hair. Photorealistic and seamless, high resolution.
