Visions of a busy city street come to mind after I read this poem.
In the first four lines, the rhyming scheme fits nicely. There's also a nice rhythm (imagine tapping your foot as you read the first four lines). Jumps along pretty good.
When you get to the second set of lines, there isn't a rhyming scheme and the rhythm doesn't seem to bounce along as easily. Was that intentional? Is it different from the first group of lines to stress a disconnection (sadness)?
The last group of lines took me somewhere different than the first two groups. I pictured a city before dawn in the late winter. Everything is melting and wet with dirty snow. The line "As night crawls home" could mean either dusk or dawn (twilight, as it is called). Either one works...but I'd prefer dawn. It's just the visual that I perceived from your words.
I did notice one thing in the second to the last line..."it's" should be "its".
