That was awesome. Love the second draft. In my opinion it gave off the feel of "preparation" for war which I think the main menu should have as its Music.
I don't think you need this but for some more inspiration look at the DOW2 album on Itunes. And look at The Green Horde Rises and the Orks theme. Or ill just put down a link...might be better so you dont have to buy it.
The Green Horde Rises:
http://www.youtube.com/watch?v=c5s04KYu-n8March of the Waaagh!
http://www.youtube.com/watch?v=Iv6Yp6scDfUThis music gives me the feel of being overwhelmed of being very upfront which i think the Ork theme should have. Also Drums and Low "beats" that seem to be rhythmic but also kinda random would make their music.
A DOW1 bonus

Orks theme.

Khaine's Wrath:

http://www.youtube.com/watch?v=X8aPNDlGYAYThe Eldar In my opinion should feel some what rushed but well thought out. And like how Caeltos said Sacrifice. I guess the best way i think would be "Dying yet powerful."
I hope this helps in one way or another.
Again though, awesome work

)
p.s. Some awesome songs I listen too when working on my TT stuff. Only a few but here they are.
