Hey gimme some feedback plz:

welcome to death i'm puttin it on your rep//
so step up to the plate so i can put u to the test//
I'll best u in a slugfest and lay u down to rest//
leave u in an alleyway wit blood on ya chest//
u fucked wit the wrong dude//
I'll have u sippin ya food-- through a straw//
I'll eventually pick out every flaw- in ya body//
I'll leave u pain inflicted wit a bullet in ya jaw from a shotty//
I'll have u zipped up in a body bag//
Or i could have u in a full body cast//
All it takes is one blast from the shotty barrel//
And you'll have a coffin about half the size of a pharoh//
I can read ya future like a tarot--- u know what it says//
the bullets I got in the clip are gonna leave u dead//
I'm gonna blast off ya head and leave the floor red//
I'm not gonna stop until I see ya body drop//
or until I see u in the street//
And ya head is severed where the curb meets//
Then what's left over I'll let the birds eat.

hmm...

too simplistic of flow... also the ryhme scheme just wasnt there at aomse point... You had no worpdlay at all
