Close-up portrait of a young woman wearing a thick, loose, plush-knit turtleneck sweater in classic Christmas tones—deep forest green or rich crimson red, optionally with subtle gold thread accents—holding the collar with her hands; soft, cozy texture; in front of a brightly lit Christmas tree rendered with shallow depth of field and green-and-red decor: matte and glossy red and emerald baubles, red velvet ribbons, deep green foliage, and soft glowing warm-white fairy lights; soft, airy window light creating a warm, cozy atmosphere with gentle shadows and bright exposure; eye-level angle; high detail, photorealistic; shot with an 85mm portrait lens; background bokeh in rich greens and reds with subtle warm highlights.
