This took about 11 hours to render at 1 min per frame. I used a lower resolution and high noise threshold to get a fast preview render. This provides a pretty good idea of what the final render will look like, but you'll notice that the high noise threshold causes some problematic artifacts when animated. I found that reducing this setting to 1/3 of what it is here produces an acceptably low amount of noise for the final production rendering.
Enjoy this preview!
