I think it’s a very credible piece of work for a one-man band operation. You do a pretty good job of using edits to move the eye around and give a sense of motion to what are mostly locked-off, static camera shots.
I’m not saying you need to add a bunch of jib and slider moves, but they would make a nice bit of “seasoning” here and there. One thing you might consider, if using 4K cameras, is shooting a little looser framing than normal, then adding synthetic camera moves like pans and crops and even occasional zooms in post, with a 2K final product. This gets you *some* of the effect of the slider-type shots without the expense and bother of the actual gear.
There are a good number of cutaway and b-roll detail shots to not just break up the static narrative, but to emphasize certain points. I was expecting a mirror or gopro XCU detail shot of the under-body weep holes under r the Mercedes, when you talked about them, but you didn’t show any.
I personally like the technique of moving the body of the presenter into and out of frame as a transitioning device, and not just always cutting from one shot with the guy in it, to another shot with the guy in it. See any episode of “Good Eats” for inspiration, because Alton Brown is masterful at this.
Nice work on getting clear audio all around outside and inside the car: many people who do this kind of work don’t do the audio as well as you have. That said, it might benefit from a bit more tweaking in EQ and compression, but this is a subjective observation on my part.
The Bin Laden joke fell a little flat for me.
I think the overall pacing could be sped up just a tad, but again, this is subjective.
Not much you can do with an English sky, shy of sky replacement, but I did see you add what looked like a grad filter effect on one shot and I’d encourage more of that for making the sky less blah.
Overall, looked pretty good to me.
