epic music The Terror

Hello,
This music is about the world after the global climate disaster. After cataclysms, the world change, and opportunists and tyrants get the power.
I was trying to describe this society with the tools of the music. 
What do you think?

It sounds very nice. I wish it had some rest, anywhere.   At 1:30... when I thought the relative calm would come, it gains in speed, which is a good effect. But the tension is in the whole piece....

The use of the minmaj "I" chord is a nice recurring touch, though I feel like its presence could be heard more throughout, since it's a great introductory barrier breaker between tonality and a hint of chromaticism. It would also help build more cohesive indeterminacy for the audience, where any chord could be off-putting and yet totally applicable.
