The timing is very well done on most parts of the track so that the comments from Jezza match the position of the car in that moment. Oh, and I like some of the cuts you have put in there, i.e. cutting to cockpit view including the view of the driver. You are right though, a Stig model is needed badly
I like it overall, not bad for what I think is your first try!
It took a surprising amount of editing to get everything to fit. Top Gear don't show the full laps and I had to add a couple of drive by shots to fit the audio. The only part I couldn't really match was the tyre exit after follow through unfortunately. I also found no way to turn off the HUD during the interior views infuriatingly, so I compromised by zooming in.
