1st track Intro too long, bass drum too loud.
the effected vocals are a waste of space as they're unintelligible, grating & do nought to enhance the track.
Your lyrics & rapping aren't bad - the offence meter went off the scale though.
Ido is right - your accent could be a benefit so use it - make it clearer & more attractive by making the vocals clearer and ditch the chipmunk bits.
