I'm no expert in architectural photography, but looking at your photo, I could not decide what you wanted a viewer to see as a subject of interest. I would say you need a better angle. If you look at the examples mentioned to compare to, you can see there are interesting lines, lighting and curves to help you draw the eye to the photo. Some of them are post processing however...
Keep working the subject, (the building and lighting) from different point of views. From your picture I would have gone to the far left and shot the lines using vertical and worked a little bit more on the exposure. Meter off your palm and recompose, or add a little overexposure to avoid the pitch black sky.
Go lower, get a bit closer to the fountains, use slower shutters to capture the water nice and silky, etc.
