The remix competition has to be of one of 3 selected songs. I don't recognize this one so I don't think they will let this one be entered.
On the other hand this is awesome, its pretty cool.
Where is the female voice from? Its beautiful.
I made a Halo 4 remix myself and uploaded just yesterday, you should check it out.
I really like the orchestral pops along with the choir. Is that a synth you have for the voice?
Thx, and no, it's not. its a recording that came with the program i used. it's something like garage band but more complex. I'm glad you liked it! ^^
