Rejection reason not clear enough please help me

 With the first image, you have some smeared elements. That may be dust, may also be bad photoshopping.

The 2 other images will get also an ip violation because of the tractor. (See known IP restrictions in the manual).

Hello,

An issue that I notice is that the colour balance is wrong. Too much blue, so it gives it a cold look; you could warm it up a bit.

Since you didn't upload full size images here it's not possible to zoom in and inspect them carefully; however in the 2nd image there's an oblong shaped bright smear of light right in the middle of the sky, and in the 3rd image, the sky appears over-processed, perhaps too much Dehaze applied?
