While the photos are OK in their own right, it is the progression of the three together that pleases me most.
It is clear to me, if these are in sequence, that you have explored this location to look for ever more interesting angles.
The first is a partial sideways view of the two bridges, resulting in arches over arches and a mostly horizontal (curved) geometry.
Although we see through the bridges towards the background, the photo does not really convey a sense of depth because there is no connection between the bridge (parallel to the photo plane) and the distant background.
The second introduces that sense of depth by viewing along the bridge into the distance. That can be seen as an advantage, but lining up the bridge with the background was difficult: there is not really a smooth flow: the background intrudes upon the scene.
In the third you have resolved that problem of overlap and distraction, but getting closer and "zooming in" with your legs. Although the focal length has remained a constant 12mm the photo feels much more like a telephoto shot, because of how the background is eliminated. The bridge has become a successful abstract composition. (You have avoided the symmetry that could have been boring, but showing more to the right than to the left.)
