The first image is about 1/4 stop underexposed, there's chroma noise in the sky, and the white balance is too blue.
The second image also has a white balance issue and the verticals are leaning.
Thank you, dear Jill_C.
As @Jill_C said, the picture is underexposed. You see that clearly with the histogram:
The whites are missing. I also agree on the white balance issue. I do not see chroma noise, however. In addition, the sharpness falls off at the borders. I would recommend correcting what can be corrected, maybe adding a small amount of texture/clarity and trying to resubmit. The image as such is nice.
I agree with @Jill_C. I would also enhance the sky by adding more contrast. In that case, you will need to correct your sensor spots as they also get “enhanced”. 2/3 to the right, there is also a black spot, probably a bird, that I would remove.
Thank you for advice.
