This song sounds awesome, I just think that the dubstep part of it could be a little better. There are not many rules, just follow them.
Rule #1 the title will say Victory Chant (Remix) by (your name)
Rule #2 the areas in blue are not to be samples, but your own sounds.
I am not really worried about the main melody, just the parts in blue, but if you change the melody, at least make it similar to the original.
Have fun remixing this song.
