First thing is first...fix your structure, keep them all the same length and not too long.

example:
Ima scream out, till i cant breath out//
And every single blood cell just gets up or gets downs and ''moves house''//
Dam keep out, im blowing streets down with my fuckin freestyle//
i aint street now....but i could be raised in a zoo and still 'keep-wild'//
I slash and stabb i crush wid mad sounds, upon the crusts of crusty mantile//

what it should look like more or less:
this is to make it longer....Ima scream out, till i cant breath out
& every single blood cell just gets up or down & ''moves house''
Dam keep out, im blowing streets down with my fuckin freestyle
aint street now but i could be raised in a zoo and still 'keep-wild'
slash & stabb crush wid mad sounds, upon crusts of crusty mantile

/\quick easy way to help the lengths, and remove the unneeded "//"

look kid you got some potential as you are already rhyming
with multies and internals...but you got to elevate
i suggest reading battles from elite frontlines, and LLL
dont pay attention to any herbs in FL or EFL

also go and take a gander at the tutorials...they should
help you immensely
