While your composition is fine and shows the stength of the structure , I find your photo lacking contrast especially below the bridge deck. This could be down to the wrong choice in paper grade or maybe problems with your scanner. At any rate I just think you are not showing your photo to its best advantage.
Thanks a lot for commenting, Vincent, I appreciate it! I have to admit, this was only my 2nd outing with the Mamiya/medium format and I'm relatively new to film. The original image was underexposed and was pushed in processing, which explains the loss in contrast most likely.
