Why do you think these photos were not accepted?

You tell us what Adobe said!

The second picture (horse) is out of focus, ill exposed and noisy. You can't save that one.

The first picture is more difficult as it is a bit to dark in the background, but the eyes are reasonably sharp, so you could work on that a bit. Unfortunately, you did cut-off the beard, even that you still had room above the beast. That is bad framing. Obviously, you are also inside a closed construction. That may trigger the need for a property release. So, I have more than one refusal reason.

Hello @Renzo16B6 , I agree with @jacquelingphoto2017 . The first photo can be repaired. You may want to try something like this:
