Well the difference between the update and the ones before were:
- shaman had the beard
- grunts did not have the dagger behind and alternate grunt did not have garthok armbands
If you are looking for more unit models with simple changes you can request on my side your ideas. Also I suggest looking into
Bagysta work. He made grunts for all clans
I made mine in order to give the original a more protective look and better equiped without exagerating too much with the armor and weapons
