This is a really good example of a related thing I've been thinking about, which is bases. Stuff like those walls (bottom left pic) have a relatively small silhouette on a relatively large round base. Unless you play treating that circular base as difficult or area terrain - which I don't think makes sense - you should treat that as empty space.
Most of the terrain you've got here isn't like that, but I've seen tables where almost half of the "25%" is actually just the bases the terrain is attached to.
