A lot of people are unwilling to offer critiques because they don't want to hurt anyone's feelings if they don't like the photo. It's easy for anyone to toss around "great job!" when they see something they like, but it's not always easy to put into words why you
don't like something.
As for my own thoughts on this photo...you can do better than this. You have the right idea, but the execution just isn't there yet. Ask yourself this question:
What made you take a photo of this bridge in the first place?
Were you just sitting around watching All in the Family re-runs one night and just leap out of your chair to proclaim,
"I need to take a photo of that blue bridge!", then speed off in your car in the middle of the night? Were you just stumbling around in the dark looking for glitterbugs and you came across this bridge? Why are you taking THIS photo?
I have to assume that you like the way the blue lights contrast against the dark sky, and that you like the way the lights reflect on the water. Assuming that I'm correct, I have to ask:
"Then why did you choose a viewpoint where there's a big friggin' bush right in the middle of your composition?"
1) Define your purpose. What about this bridge speaks to you? When you answer that...
2) How can I best show what I like about this bridge? And then...
3) When can I best show what I like about this bridge?
On a technical level, this photo is not very good. It suffers from composition issues with that bush in the way, and whatever that strange red glow is coming from the left side.
Solution: move to a different location. Find a better angle, preferably a location that is closer without as many distractions. Can you get to the spot near where that boat is? It's closer and it looks like you can get right out on the shoreline without anything in front of you. Can you get directly under the bridge? That would be a cool shot, too.
This photo is also too dark. Perhaps try shooting during the
blue hour, use a longer exposure, or try HDR if you have the means.
