What are the most negative sounding words in the last six stanzas, and why do you think the poet has chosen them?

They’re gone now, all we have left of them
this vast concrete-and-glass mother-ship

that seems to have landed awkwardly
in our midst. And Westgate’s dark

with November rain, but different, as if
the stones retain heat, secret impressions

of shoulder-blades, shallow cups,
as sand would do. The grey façade

of the empty auction house, three storeys
of boarded windows, doesn’t look sad,

more like it’s closed its eyes, breathing in
the smell of sweat, sunblock, confidence.

Does that choice of word here make the whole poem more negative overall?
