Forget it it was taken at the correct fstop exposure etc.. if i tilt it to the right so the building is vertical it makes the lampost on the right even worse.
If i straighten the lampost the building looks like the leaning tower of piza.

Or is it ok as it is, vertically i mean.

Thanks for the advice - i don't fancy a 100 mile trip to see if the lamp post was crooked after all.
It was my first time photographing large buildings and now i see the keystone effect as mentioned above, i will try to be more aware when doing it in the future.
