Berliner Bridge

Okay, to start with, I really like the geometry in this composition. All the strong lines lead inevitably to the intersection of the top left third... but in, fact, it's not even the third. The rule of thirds is actually a simplification of a more complicated concept based off golden ratios... I don't know if it was intentional, but you seem to have nailed that ratio.

The grays in the image are just gorgeous, giving beautiful gradients without losing detail and sharpness. And by using a long exposure to blur the clouds, you've created a wonderful background for the bridge.

My only complaint is that the very top of the image is a bit too dark, and creates a loss of contrast with the guide wires in that upper part of the image. It's certainly not a big problem, but perhaps something to consider.
