Took a quick look and I must say that your work looks promising. And as strange as it sounds you seem to have overnerfed the units. My comments might seem harsh, but that's just because I like your mod and hope to see the finished version.
Battle Maiden - Hits hard but can't take a punch. 10 hp is bit low, and high defence is negated by berserk. 60 gold seems excessive since they will be hard to keep alive.
Crimson Rouge - Great unit concept but way to expensive. Especially since they got such low morale. I would put them at 12 gold.
Crimson Guard - No way that I'm building these guys. The stats are not worth the upkeep. 15 Gold sounds a lot better, since they have nothing save their low resource cost to show for it.
Stalwart - Heart Companions by another name, but cost 10 more resources. Sacred castle defenders is not that optimal since defence often comes as a suprise, and these guys can not be built in the numbers needed to make the bonus count.
Devoted - Worth more then a mere 3 gold. With a even a modest bless strategy these guys are already strong units (morale 15 plus shield and javelin).
Dark Lord - Too expensive in both gold and resources. Death 3 sacred knight commander is a great thug. Two heads, trample and selfblesser is a bit over the top. Trampling actually makes him a weaker unit.
The casters - Are pretty well balanced, if perhaps a bit too similar. I would either turn them into the classic three tiers of power, or give them more individual flavor (resistances and survival abilities?).
Crimson Commander - Why would I invest in this guy instead of a 40 gold independent commander with the same stats? His sword alone makes little difference. His sprite show him using a shield. Why did you chose to give him a crossbow?
Gold Standard - Good concept for a unit, and a great way to make sure all your units are blessed. Should be expensive but 300 gold and 65 resources are too much. He's a good deal better then Pangeas priestess, but not that much.
Kunoichi - A really poor assassin. Low damage and weak stats makes this unit hard to sell. I would much rather buy one caster then two of these. Give her sacred, priest 1, dualwielded daggers and full leather armour and she looks much more attractive.
Your pretender feels overpriced as well. 75 points seems more appropriate. He's basicly a thougher version of one of the cheap rainbow pretenders.
