Still workin' at it. I'm supposed to be grounded right now so it will be a while. (smart-mouthing my parents)
Surely being grounded should mean that you can spend more time on the video?! hehe...
Having just watched the preview again, can i agree with the suggestions made about dropping the Metallica track. GT's never been about pounding heavy metal (sorry to disappoint, it's good but not the right place for it).
If you want to keep the dance track at the start, perhaps tryp clipping or stretching some of the clips slightly so that all of the transitions work with the music (another point already made i know).
After the panning shot over the roof of the F430, instead of cutting to a front view, have a search for any video of it pulling out of the garage OR cut (with a tween (gradual fade up)) to the shot of the Nissan GTR pulling out of the garage from the High Performance trailers

I think that should make the section flow a little better because at the moment it jumps from sat in garage to on track.
Music wise, i'd like to suggest We Come One or Insomnia by Faithless. Both have really strong baselines (allowing for rapid flash cuts and stutters (like those in several of the GT5P trailers) and also build up into a crescendo (peak) which would create more tension and make the film more immersive.
Sorry if it sounds like i'm ripping your work to pieces, all my comments are meant as constructive criticism. I had the same things said to me when i started making promo videos for events and it's improved my video composition and editing no end!
Good luck and i can't wait to see the end product! Perhaps on the 28th march or the 17th april?
