30 seconds without anything? What the heck you had in your mind? lol. Ok, when you combined all your instruments together, i lost the rhythm, You have to put the right place on your instruments, so it wont sound disorganized! And, it was boring because, like i said 30 secs without anything, it doesnt have a lot of instruments, plus the whole song is being kinda repetitive :/. You can improve!!! i hope that!
