Understanding White Balance

fringing and artifacts can be seen at 350%. Look at the bird.

@reedesign1912 did a good job on this! Maybe I could add that the picture is underexposed as shown on the histogram:

(no whites, half of the highlights are gone).

The upper-left corner is disturbing. I consider the different dust patches as on the window, but I would anyhow clone them out.

You should also keep away from making "artistic" looks, the more natural, the better it is.

The picture will throw an IP violation, as the building looks quite iconic.

In my opinion, the white balance is off and the image is too blue.  The colours also seem to be over saturated.  The whole image needs to be rotated counter clockwise so that the building is level on the bottom and ideally crop out the blurred plants in the bottom left corner.  There are lots of marks on the windows (may be reflections from items inside, could be dust on your sensor, could just be dirt on the actual windows.) I would clean up those spots / clone them out.  Around the seagull, there seems to be a bit of a halo as well that should be fixed.

I am not sure if the building is recognisable to the owners.  You may have an IP (Intellectual Property) issue as well that would require a property release.

I hope this helps you out.
