Nice colors in the greenery!

If you want to maintain the wide angle look, consider cropping to eliminate all of the foreground sidewalk, which is uninteresting and occupies about 25% of the image. Doing so still leaves the cars, which are unattractive. I wonder if you used a longer focal length from the same position to get a nice image of just the dome and the trees, though admittedly not at such a wide angle.

I'd suggest having a look at something even more aggressive that suggested by Mike.

Go the extreme left hand side. See the concrete through the trees. Crop just at the top of that. You get some like a 2.5:1 panorama that you might like the look of.
