A highly detailed, heartwarming Christmas scene featuring Santa Claus sitting in a wooden sleigh filled with colorful wrapped presents. Santa is wearing a classic red suit with white fur trim, red gloves, and holding a glowing golden heart made of sparkling light in both hands. Two cheerful reindeer with large antlers stand in front, wearing red harnesses decorated with golden bells. Snowflakes fall gently in the night sky. Cozy wooden houses with glowing windows and snow-covered roofs sit in the background, surrounded by pine trees. Warm yellow string lights hang overhead, casting a soft holiday glow. The sleigh glides over fresh snow illuminated by lanterns attached to the sleigh.
