I'm just the opposite - I love those acid-trip colours!
Fantastic mod all-round. I especially like the backround concept, it's exotic but believable, not easy concepts to combine in one thing. Good job with that.
I don't like the nonplayable (Human1, Clone1, etc) civs. Personally I think you should cut these out, it's kinda mood-killing when you're playing in this futuristic enviroment and a warpainted Viking or fur-hatted Mao pop up.

I used Conquest Editor to remove 'em on my copy of the mod, and it runs fine without them.
Other criticism I'd have would be about other minor things - incomplete advisor heads as mentioned above, some civilopedia syntax errors or links to 'invalid entries', and so on - certainly nothing game-spoiling.
Overall, as I said, really great mod. Looking forwards to more updates.
