Very nice - I had a similar play smaller scale over the Christmas break.
This is one of the better ways to learn what the car does. It's also an excellent way to train your reactions for a tail out scenario. Like any kind of reaction training you have to do it repetitively many many times, and despite how it looks, this isn't hard on the car.

Normal spirited driving is way harder on the car than this as there is so little grip the car will slide and spin quite easily without wild reving or clutch slipping or the associated high loads on components and the snow has never marked the body of any car I've done this with. Just don't do it over gravel or pot holed surfaces etc!
This one's a keeper
