Hi @Renato_Mendes
The first photo has a white balance issue. It seem to have a slight blue/purple appearance on the wall. I'm not sure where you placed your focus but might be a little too far on the landscape. The sea color looks a bit over-saturated.
I'd say add a little more exposure to the second file. A small amount of grain noise is visible in the water in the forefront. Again there might be an issue where you placed the focus.
The third file has a white balance issue. The road is slightly blue.
Please zoom into your file at 100 to 200% to view them for errors.
Best wishes
Jacquelin
