A picturesque winter street scene in London featuring the iconic Big Ben clock tower in the background. The street is lined with colorful buildings on the right, decorated with festive holiday ornaments and snow-covered rooftops. On the left side, ornate street lamps are adorned with red and blue floral arrangements, casting a warm glow on the snow-covered pathway. Snow gently blankets the ground and softly falls from the sky, which is filled with glowing lights resembling snowflakes or festive sparkles. The atmosphere is magical and serene, with vertical framing, vibrant colors, and soft lighting for mobile wallpaper.
