A close-up view of a decorated outdoor Christmas tree during snowfall. The tree branches are lightly dusted with snow and adorned with red and gold baubles. Warm white string lights are wrapped around the branches, casting a cozy golden glow. Snowflakes gently fall through the scene, and the softly blurred background enhances the ornaments and lights in the foreground with warm bokeh effects. The atmosphere is festive, serene, and magical — perfect for a winter holiday mobile wallpaper. Render in ultra-realistic style, soft lighting, crisp details, vertical orientation.
