I really like it....the reflection tops it off. It's been photographed many times from many angles but found a fresh view.

Just a couple of slight suggestions.
There is something in the sky on the left of the arch. Possibly the 'daylight moon'. Personally I find it distracting and I would clone it away. If it was bigger I would leave it.
Also there are a couple of spots in the reflected arch, possibly caused by ripples. I would clone these away as well.
But these are just very minor points. Otherwise a good image from a perfect angle.
