It's ok, but could be better with a different crop or if you can re-shoot it. I would reduce the space above the bridge, which would inscrease the space given to the water and the bridges reflection. As it stands now, it's about 50/50, while 1/3 above the water line to 2/3 below the water line would be just about perfect. The woods above the bridge doesn't ad anything to your composition, and just serves to make it busier then it needs to be.
BTW, why did you decide that you needed to do this as a HDR image? There isn't a very large dynamic range to be concerned with.
