Merry Christmas to you too!
I was very impressed at the animation at this; it seriously looked like it could have been CGI! It was a little hard to pick up the Christmas theme until the end. While you certainly weren't aiming for a story as you stated in the author's comments, you didn't need one. You gave the audience everything they wanted in a brief cartoon. I kept thinking the snow guy was Catface at the beginning because of his head shape. Sure, there wasn't much of a background or anything, but simplicity is all you need for this.
