I feel that the sky in #1 dosen’t really help the image and
maybe there is a little bit too much of it.
You could try cropping a bit off the top.
I think the area to the RHS under the bridge could do with a
little lightening (maybe the Shadows/Highlights tool) to bring
back a little more detail.
The tower and the wooden planks in #2 make a lovely subject.
The railings around the ladder (Not your fault of course) don’t
help the image I think.
I can’t help wondering what the colour version of this was like.
I quite like the sky in the first image, but I like that king of thing anyway. I wouldn’t be in any rush to crop.
I do agree with John on the second image. It works well in B&W but as I love to see clear blue skies I wouldn’t be adverse to seeing the colour version either.
