Really good. I don't see why people have to analyze the hell out of things when they're perfect exactly the way they are. The descriptive words are good. The kind of 'removed' affect is nice.

I like the sense of foreboding in this poem, and the fact that we are in an urban setting where "who can tell the sun from smog." The phrasing of that idea in question form is also a nice touch because it makes the reader pause. I wonder what those "creatures of the night" look like...perhaps a line detailing the sort of image the writer has in mind might open up the poem and remove it from a purely gothic atmosphere...Nice work!
