Thanks for playing, glad you liked it so far.
The coloring of units are pretty odd-looking. I just can't really put it to words, but they look really unusual.
I think I know what you mean. Units change colour slightly on different theatres (most notable for the Soviets) which isn't perfect and I'd like to increase voxel shading contrast a bit.
Also, this mod needs more countries. But so far, the Beta is pretty excellent. But I can't seem to activate the soundtrack, though. :/
The downloadable soundtrack or vanilla? You should only need to extract the mod soundtrack into the same directory as the mod. The YR soundtrack copied straight from the CD should also work fine but the Red Alert 2 theme.mix needs renaming to be read by YR. Something like ecachera2theme.mix should work.
