My first song with my first sevenstring guitar

[Bence Póczak]

Hi ! What do you think about my first song on m first sevenstring guitar?
Guitar sound comes from a pod xt live.
Guitar is a schecter omen extreme 7.
For drums I use superior drummer 2, and EZmix 2 for master.
I don't have a bass, I used pitch shifted guitar. It's better than nothing...
Any advice to make it sounds better?
