The second shot is sweet. I'd crop enough from the top to ease the bull's-eye placement of the wall and buildings--the shot's dominant elements whose impact would be enhanced. Might a bit of perspective-control work in the far right corner of the building? Any chance of cloning-out the(distracting) clutter under the distant bridge on the left? Weren't it for the stack's lettering, a 180 horizontal flip would pull the eye into the shot as it follows the sweep of the bank. As is my eye hits dead centre first and stays there.
I see the first shot as a warm-up for the far better second one.
Purely my taste but I'd experiment with a monochrome version of the second shot. Curious if a red filter effect would lend some drama to the sky and water? Playing with contrast alone would open the way to another "look." You deserve more comment here than a cursory "nice shot."
