The flow of the lyrics seem pretty good, except for some parts (the "Some things in my life..." stanza). When I was rapping this (I cannot rap well btw XD), like I said, some of the verses didn't follow a consistent flow. That's just me, though.
Not sure if that's what you're looking for, but that's what I've got. I just love the conviction and determination behind these lyrics. Something I can relate to right now. Look forward to seeing more!
