I'm impressed.
What did you use for the snow? It doesn't look like the sugar or flour that most use.
He seemed to turn slightly too suddenly, and the stop could have used some animation on the minifigure, but other that that the only flaw is the jerky focus changing.
If you wanted to take things to the next level, you could have animated the minifigure all throughout the clip, but that would have been difficult and not entirely necessary.
Also, did it export right? It's not filling the player. There's a black border around the edges.
