Nice photo, Mr.Freedom. The perspective is great and I love arches. You could do so much with this.
My eyes do keep getting dragged off to the lamppost on the right, so you might want to consider cropping the photo to cut it out...
or you could make it a feature by including just a section of the right hand side of the photo - but you'd lose that symmetry. Of course, you could make a triptych, displaying different versions or cuts of the same photo. Another possibility would be to take either half and copy, flip horizonatally and stitch it on so you have a perfect symmetry - although whenever I've tried this it looks fake.
I was looking at the people at the far end of the walkway and thought this location would be good for a series of photos in a slideshow where the people seem to jump closer and closer and then become a blur as they move past the camera's field.
I hope you play around with this image and post the result. The photo is worth your effort.
