my song with sonar x1 guitar instrumental metal

There's nothing wrong with your guitar playing.  You are very skilled, and you can rip through those scales at the speed of sound.  You are definitely a contender in the thrash metal category.  But, that's all this piece is; fast guitar licks.  I don't really consider this a song, per se, but rather, a showcase for you ability to play fast guitar licks.  I suspect that there's more to you than this, and that is what I'm waiting to see.
