I don't want to speak for another comment, but I think what David means is there doesn't appear to be that much difference in dynamic range to start with that would require using HDR. Maybe just some good processing in Photoshop or Lightroom would bring out the same results here.
With that said, the scene if overexposed in the original shot would certainly lend itself to HDR. You have kept "the HDR look" to a minimum. I can also see the scene as you probably did and feel comfortable with the representation as being fairly accurate to your memory of the event.
Not all HDR shots are rusted out trucks and such. Anywhere the camera sensor cannot truly capture the full dynamic range of a given scene is a candidate for HDR. Only you know what the original details were.
Or I could be totally wrong in my assessment...
