Nice work! Even if not totally accurate I love the scheme you've got there. And the snow looks really cool, never thought of just a little sprinkling of it on the vehicle like that. And you can always go back later, remove the figures and clean the mold lines off them, no big deal.
I built the kit some years back but she didn't come off quite as good as yours, typical Tamiya modern kit quality, I'm surprised more people don't build them.
