Your right.
The swordsman arsenal of the undead is very skeletal-heavy.
I think the idea is really good, and the unit actually looks nice. Just three things:
1. It's something very dark. (So ... the Black Knight would be jealous at the sight. ^^)
2. What are the two pieces of cloth behind the unit? Since these are rigid, they look a bit strange when the unit moves.
3. This point is completely personal so, I'm just a bit picky. It is not meant as a critic, more of a train of thought:
Due to his weapon (a mega mace) and the winged helmet, he looks more like a Deathguard-Executor (also an elite unit) and not a "Frontline-Deathguard".
