>>2847755PP looks OK to me, but the combination of wide lens and fast shutter speed aren't working. You need to go down to at least 1/125 or so to get enough background blur in shots like that.
Here's an old one of mine, shot at a similar focal length (70 on FF), and even at 1/60th I feel like I could have gone slower.
>>2847793>There would have been no way to make a photo of this scene in a way that was good or interestingSad to say I kind of agree with this. It's really hard to get a decent photo out of parked cars, especially when they're tightly packed, unless there's something else going on to make it interesting. (Pit crew working on the car, or the car is just something really unique and noteworthy, etc.)
