oh hey, everybody, sorry for the late reply. Thanks so much for your kind words! And yes, we won the contest, so that was fun news.
In terms of technical info, here's how it was done: shot on a Canon 5D, in 3 separate setups, one on the hood, and one on either window (plus the wide establishings). The camera was rigged with a reinforced suction-cup mount, and sound was taken from a single wireless mic above the rearview. There was a bit of mild colour correction, but it was mostly untouched.
thanks again for the support, we'll be making more in the future, so I'll be sure to add to this thread when they're ready
