There's a spot on the right hand side where the top of some tree's are exploding with orange (sun)light and that's extremely distracting. The bridge is a sort of boring subject in my opinion, the diagonal isn't really strong enough to bring much visual interest and neither is the all blue grafiti that ends up almost blending into the bridge. No matter where I look at the photograph my eye always ends up on the overbearing spot of orange light.
The color's are interesting, and aside from the slight halo it looks like you did a good job processing it.
