Its missing something....
I think that your song is very good! with that being said I think that you missed the point of the original song. You know the darker deep-spacey sound of the old song, I'm not saying that you didn't know what you where doing when you made this song! I'm saying that It doesn't have the same feel..... Well time to go back to searching for a remix of Nonaggression from Sonic Advance 3.
