The first image is underexposed and blurry. It also appears that you've applied a vignette which is not permitted. There are also some identifying marks which would have to be edited out in order to avoid an IP rejection.
The second image is also not sharply focused.
The third image is also underexposed and has many identifying marks.
The fourth image is underexposed in the shadows, and not sharp enough.
Denoise can cause a softening of the image, so should be used sparingly.
