Examine images at 100-300% magnification. That's when flaws appear.
First image, too blue. And I have no idea what it's supposed to be.
Second. A nice image with some white balance issues. Also what appears to be some chromatic aberation (blue lines) on the building.
The birds in the second photo also need to be removed.
Rejected for quality issues! No surprise. The fish (?) photo is too blue and a black blob and way underexposed!
In the second photo, what are you trying to show? What is the commercial appeal here?
Also, when enlarged to 100% or so, the actual quality of the photo isn't so good. Was it taken on a smartphone?
The first has multiple issues, besides the blue blue tint, I would mention shadow clipping, missing sharpness (what should be in focus there), artefacts:
The second has (colour) noise
and is missing sharpness. You will need probably a property release for the building.
