I like this a lot, it's like aquafina said it's deep enough that it feels deep but not too deep that i don't know what you're trying to say, you walk the line perfectly. the flow is generally good, a couple places it feels a little awkward or forced... in particular the second line feels a little long and "required" feels weird, i would just say "takes concentration." last two lines i really really like what you're saying but last line seems a little long, i would just take out the always and it'd be good. but i didn't write this, i don't really know how it flows and whatnot, it's your shit do what you want, it's great as it is you know what you're doing. i could see this as a song
edit: i really like this sequence a lot:
No parents growing up, no sense of streets
No dollars to buy a meal, no cents to eat
I clench my piece as I walk by, tension seeps
Seams break as I approach, I sense release
Cock then squeeze and then I dispose with ease
Silence leaves as sirens scream
Turn and run as I spy police
I die in peace before I subside my knees
rhyme scheme is sick there. before that though it's not as complex as i would like, usually just one syllable... but that's fine, you're telling a story i dig it
