Zoom your image to between 100 and 200%. Take a look on the trunk and branches of the trees in the background at the right of the frame. you will notice that there is a display of purple color. That should not be there. Even the monument, towards the lower right side, there is a purple line that should not be there.
The shot is a little cool; meaning it is slightly blue in areas where there should be white, hence a color balance issue.
In addition to the technical issue, the file displays excessive noise/grain.
The issues may be corrected using a photo editor such as Photoshop (Ps). In this case you will need to adjust color temperature, possibly exposure, noise and lens adjustments.
I don't get the impression this was taken in RAW. If not major corrections sometimes causes further damage to the file.
Thank you for that info! I never saw that!
As mentioned, you have what is called chromatic aberration.
The overall sharpness is also not so sharp.
