|Howdy from the Critique Club...
This image has two assets that I see right off the bat - visual interest and angle. The bridge itself is a good subject, and the angle from which it is shot is appealing.
Visually, the bridge is interesting enough alone. There are many other items in the picture that tend to compete with it for attention. The machinery in the lower third of the photo is a bit small and difficult to see with any discernable detail. I believe a tighter crop would be quite nice, leaving the bridge and sky, and removing the distracting elements at the bottom and on the left side. Perhaps a shot from down in the railroad track area, looking upwards toward the bridge and sky would also work well. That, of course, might not have been possible, and I understand.
I do wonder what the shot might look like in natural color. The desaturization you have used is effective, but the shades and tones are all so similar that many of the details have been lost. The sky, however, does look quite stunning and works well with the colors you have chosen.
The title you have chosen is nice, but for someone who is unfamiliar with bridge demolition, it was difficult for me to see that the bridge was actually being torn down.
Overall, this is a good photograph with some positive elements and some points upon which to improve. I have enjoyed studying it and wish you the best in future challenges.
