I don't know how to feel about the changes. The tall buildings take away the view from there but the buildings themself ain't too bad looking. Plus the addition of all the trees helps a lot.
I think the 1963 picture looks empty and bleak. Between the higher density businesses and homes, a museum, lots of trees, more people walking around, wider sidewalks, no overpass that's more difficult and less safe for pedestrians, and safety measures like a pedestrian crossing with lights and wheelchair ramps (and no median that's impassible for wheelchairs), the 2019 picture looks way better to me.
