A joyful child playing near a beautifully decorated Christmas tree, wearing a cozy sweater and a Santa hat, surrounded by wrapped presents and glowing fairy lights. The scene is warmly lit, with a soft golden glow from the fireplace in the background. The child is holding a toy and laughing with excitement. Snow is lightly visible outside the window, creating a cozy holiday atmosphere. Ultra-realistic details, vibrant colors, and festive cheer.
