The picture appearance is as would be expected for the camera and ND settings.
Based on your analysis of what you feel is 'wrong" with the shot and other comments, what you want changed is the "pseudo thin DOF effect". This occurs due to motion blurring of trees ahead of and behind an object which is in focus PLUS somewhat 'sharp' objects in the background.
An 'improved' result which may or may not suit is to increases aperture to reduce true depth of field and to bring the focus point much closer to the camera so that the building to the left is towards the rear of the field of focus and just starting to 'blur'. The far distant buildings will then be wholly defocused.
You may be able to get this reduced depth of field with f22 but probably not. Increasing aperture from f22 will mean your ND filter does not have enough attenutaion, but you can just reduce exposure time accordingly. As you are using 1 minute exposure you can reduce exposure time substantially and still get near total blurring of foliage due to wind motion. eg changing from f/22 to f/11 will require an exposure reduction of (22/11)^2 = 4:1 = 15 seconds = still fully blurred foliage. Even at f/8 you'd need 7.5 seconds and would still expect OK blurring of foliage. I'd expect you could probably reduce DOF enough as above at f/8 so that the middle buildings were towards the rear of the true DOF.
Whatever you do is going to be a compromise as you are attempting to adjust the "reality" that the camera sees. A true partial solution is to use a true tilt shift type arrangement to somewhat undo the effect, but motion blurring are liable to always be perceived by the brain as DOF effects, or you can 'cheat' with multiple images and/or post processing.
