I am not an expert in this style, so take my info for what it is.
I like the presentation of Akademic, it flows quite well.
I know it is part of gangster rap, but I am not a big fan of vulgar language in any type of music; therefore, I did not care for Pressure.
Take your music to the next level; see If you can find a keyboard player who can help write some interesting riffs to fit in with your music to make your product stand out a little more. I think too many "rappers" rely on preset beats and samples that after awhile it looses its orginality.
