I actually listened to your tracks, the first one and last one's were decent, good beats good flow. I'd have to say you do have a voice and flow that works for rapping, but, voices aren't really important to most people(Guru did well for himself with a completely monotone one). Some of the other ones though had too much of a raver/electronica/lets pop some X and hug-type vibe to them that I couldn't dig.
And how about rapping about selling drugs, running in gangs, murder? Even if you don't actually take part in these activities you can still rap about them and the general public will accept it as truth no matter how much information comes out saying otherwise. Examples: Mobb Deep, Nas, Jay-Z, Rick Ross, Lil Wayne, Dr. Dre, The Game, every popular rapper, etc. And other than Nas, you're actually better than all those rappers.
You need to kick up your punchlines or whatever though. No one wants to hear that you "get high like a plane".
Sample of proper plane punchlines 3:05-3:15
Error 400 (Bad Request)!!1In summation: deeper punchlines or don't keep it real.
