Rukunetsu - instrumental (which you can find here)

MC Final Sigma - rapping vocals

Hey everybody, MC Final Sigma here experimenting with a new style of rap for me on one of Rukunetsu's excellent beats. The instrumental is a remix of Brenda Lee's 1963 cover of Sinatra's "Fly Me to the Moon." Since the beat is already totally legit, what I'd really like feedback on is the vocals. In particular:

1) I know next to nothing about vocal mastering, so pointers would be appreciated (I'm using Audacity for this), and

2) Since this is a weird, sort of inhuman delivery, some friends have suggested that it might sound good with a robot voice filter of some sort. Again, I'm not sure how to do that or even what type of robot voice might sound good. Any ideas?

Otherwise, general feedback would be appreciated! Thanks!

I think that a robot voice filter would be cool to try out, definitely. I'm thinking less "Twilight-Zone-60's-Automaton" voice, and more "Trent-Reznor-Scratchy-Semi-Human" voice, if that makes any sense. I think that'd be fun
