I think those bikes really distract from the subject of the photo. If Amsterdam is your subject, the bikes shouldn't take up the majority of your shot.
I find the railing and bikes leaning against it to be distracting and obscure the whole bottom half of the image, which greatly detracts from my view of this beautiful town and canal. I don't find the bikes or railing add anything to the picture. In addition, I find the lights a bit too bright.
I would have looked on the other side of this bridge, a much more interesting part of nightly Amsterdam. Btw, that looks like my bike, stolen of course.
I would like this better if it were zoomed up past the bikes and railings. Excellent subject and one that lends itself well to being photographed. Great subject and not a bad photo either.
