Nice video, looked like a damn good time.
Who was driving in the first in-car footage? Looked like a fantastic job with sideways for 99% of the track loop.
Who were the editors? I saw some Will Roege influences in the video :thumb
More angles and variation in the video, it should be telling a story with a beginning, middle and end, lots of room for improvement, but not amateur either. I highly recommend getting one or two car mounts and using 3 or 4 angles on a car through out the day to edit in later. I also strongly advise a use of a fluid head tripod for the entire day. Makes a night and day difference in the overall feel of the film.
