If I tell you that I had no idea what a Talon is and even after watching I have no idea what DSM is then you'll have some idea of how limited my knowledge of what you're trying to achieve is! Therefore my comments should be taken as from someone who doesn't have a clue what they're talking about.
I like your ambition, but I'd like to know what you consider "decently done" and what you think this ha sthat others don't. From my point of view it looked like many other car vids. It's unusual to see one slightly desaturated and I admire you for trying that, but presumably the shiny oversaturated look that we normally see is there for a reason - it makes the cars look more exciting.
The overcast sky also made the video look rather dreary.
Most shots were "OK" rather than prefect - the glidetrack and (pseudo?) crane were certainly better than I could manage, but still need to be smoother for a "posed" video like this.
Mostly the shots seemed standard, but here were one ro two where I thought the framing was way off - eg 1:06 the car is inn the top half of the frame (and fades into the white sky) but is uncomfortably cut off across the windows.
I also found some of the shots held too long before the car entered or after the car left the frame.
It's not bad, but there's a lot of competition out there. With a film like this, where you're basically filming a "model", every shot has to be absolutely perfect and I'm sure that'll come with practice.
