Hi @diegof6429125 ,
The first photo is completely out of focus. It is also under exposed. That cannot be corrected.
I like the mushrooms in the second image. While you do have a depth of field issue, making too much of your photos out of focus, if you correct the white balance issue this might be accepted. The image is too blue. That too is slightly underexposed. The third image is underexposed, and too much is out of focus. It too has a blue cast. I do not believe this can be corrected for re-upload.
The composition of the photos is bad as well. Sloping horizon in the first photo - landscape.
Have a read of this from Adobe about how to create better photos:
