First of all this is avery nice image... the cars and electrical wires aren't very much disturbing.
Given your desription I knew what this was about, otherwise I had to look very closely to identify that "little somethings" as cars. I'm not very skilled in editing pictures but here at Caedes are some guys who could really help you to work on this.
I like your picture as it is but I also find it worth working on it.

Hi there..well, if it were my photo I would crop away the 2/3 rds on the right side, in other words just leave the one third on the left..Just keep those trees and the water in front of them. I find they have great colour..and the other part of the photo has too much light and the intrusion of the cars etc...but thats just my opinion...

I have to agree with verena above, it would help keep your eye from wandering, I also find that taking a pic in the full day sun, it tends to wash the colour out hope this helps in some way. As is i still like the image, and give it an 8. Peace and happiness in all ways. Dwight.

Picture looks good. If you hadn't said anything, don't think most folks would notice the cars on the bridge. When viewing full screen my focus was drawn to the skeletal tree in the middle of the others. Good pic

There are cars???
Oh ok, I see them now.
I honestly HAD NOT noticed...I was so drawn to the river bend and the glorious colors.
