Serj Tankian - Figure it Out (DND Mix)

Ok, I think I've got it now. I re-recorded all of the guitar parts, and tweaked the synth/bass. I cut some of the vocals at the end because it started to sound crazy and out of sorts.

So a little background on this. This is a remix for a contest being held by Serj Tankian. He gave out all of the tracks that make the song Figure it Out. I used only the vocals, drums, and solo guitar work. I added everything else. There is a new guitar riff, synth/bass, and what I call creepy vox for atmosphere. I feel my version has a darker, more metal feel than the orignal. Thanks for listening!

Serj Tankian Remix (rough mix)

So I am working on a remix for a contest from Serj Tankian. Please give me some advice, I feel kind of stuck and not sure where to take this mix. Near the end the song isn't finished and sounds like a big mess. Please any advice is appreciated.
