i personally use http://www.twcenter.net/forums/forumdisplay.php?2102-Culture-Identity-Unitpacks-(CIU) for the eastern + nomads + dacians + iberians

Legionaire's Mod is good for all other stuff. Doktor makes a nice one for the germanic tribes, For Gallic tribes you can also extract stuff from Haegemonia mod and use these. Kaziel's packs for the Romans

Good uniform colours

screenshots i made are usually a combination of these

Oh could you maybe direct me to some of those? I cant seem to find any decent ones in the Workshop

i've decided to just stop using the mod, a shame though but there are many good ones out there too

This happened to me as well yesterday, such a shame there aren't any slaves carrying that shield =(
