While I am convinced it was great fun testing this technique on this very photo, I also think that actually there was no real NEED for HDR for this photo, this scene, and this time of the day (?).
The horizon line totally throws me off this photo, though, cutting through the frame in the absolute middle, dividing it into two equal halves.
But you got so much room around your primary subject to the right and the left, you can easily crop this and give the horizon a place where the entire photo will gain some more "tension".
