Hi Wayne,
The most relevant bit of C&C might be to ask why you chose these exposures?
One is under-exposed and the second is blown in the sky.
You have obviously cropped in PP (or perhaps by choosing an aspect ratio at time of shooting jpg), so why not attempt to fix the exposure in PP? Or get it right at time of shooting?
I appreciate you may be trying to convey a mood with them as they are, but I think you've over done it
BTW, I had to edit your post to add the EXIF data
Compositions are fine for me and horizons are level, which is good, I would second Dave's request to see them bigger.
Hope that helps,
