I wouldn't say monotone, I see what people mean, but that style you use works. It reminds me of GLC or Guilty Simpson. First song was tight, your rap over The Watcher was ok.
The beat on the 3rd one is ok, the ad-libbing in the background is annoying though.
The track around 10:20 needs to be longer, that track is sick as hell. Awesome beat and your flow is really nice on it.
I'll listen to some more of it later, I'm tryin to leave everyone some feedback for now though lol.
The only thing that needs work is the EQ on your vocals. The volume seems a tad bit loud and the sound quality seems a bit lower than that of the beats.
Overall though, I'm likin your work.
