In a word.... nothing.
There's nothing wrong with you... except the fact that you make nu-metal. It was done well so I'll score it high... but it is nu-metal just like every other nu-metal song... always thinking there is something wrong with them but if they just listened to all the other nu-metal bands they'd realize that it's not them it's EVERYONE... ... anyways this sounds like Slipknot. Which is either a compliment or an insult depending on if you like Slipknot or not... I don't. But it means that you sound as good as a professional band, so that's a good thing. Anyways I voted 5 because this is too well done for me to vote any lower.
