Illustrate a cozy and inviting winter wonderland scene, featuring a group of friends gathered around a crackling fireplace, sipping hot cocoa and sharing stories, with a 'Merry Christmas' sign hanging above the mantle, and a festive Christmas tree in the background, surrounded by snowflakes gently falling outside.

Design a whimsical and magical scene of a reindeer and a sleigh, adorned with sparkling lights and ornaments, soaring through a starry night sky, with a 'Merry Christmas' banner trailing behind them, and a faint outline of a snowy landscape below, with a hint of moonlight.

Create a vibrant and colorful illustration of a snowman wearing a Santa hat and a red scarf, surrounded by festive holly leaves and berries, with a big smile on his face and a 'Merry Christmas' sign above him, set against a bright blue winter wonderland background, with a subtle snowfall effect.
