Sounds like Duke Nukem music or something, :D
Lol, its awesome, i love that squeeky guitar, :P
Good job man.
You ARE doing pretty good for a 12-year old, just keep at it, and if you're good enough, make music-production part of your future, as well as God, :D
But if music doesnt get good enough for you, then quit, :( or just stop making it so frequently and look for a job, lol.
kk, later.
