I'm really big on imagery carrying the meaning in a poem, and you've got a lot of it here. Strongly. Lines/phrases/images that especially stand out to me: "grit of smog and suburbia" (I don't know that you need "harsh" here, though. You've chosen this phrase so well, that harshness is implied and understood automatically. Good.) "in the dead of its night, In its rot and rebirth"--I like this, too. The alliteration of "rot and rebirth" is neat, linking two words with opposite meanings. The juxtaposition works well. "Walk the throngs and masses of uncertains, Touch and rub against the elbows of unknowns"--I like the way you use the words "unknowns" and "uncertains", as if they were tangible things. Unexpected. And while my personal taste is not to use two words when one specific one would work ("throngs and masses"/ "Touch and rub"), I just realized that it does sound a lot like Whitman, here, and this word choice is why. :) "Humble yourself to the myriad faces"--I like this very much. It strikes something inside that I can't quite put a name on. (Exactly what most poets strive to do to thier victims. . .er. . .readers!) "In the pools of sweat, blood and tears"---These three (blood, sweat and tears) are used together so often that they've kinda lost their poetic punch. They're not necessarily bad, they're just not as strong or fresh as some of the other lines you've given us. Feel free to toss out anything you feel doesn't apply, of course. Normally, I tend to dislike city-ish poetry, but you've done something intriguing, here. Thanks for posting it. Lu
