What Pirate hair was used for your dwarf?Does it fit with chain-mail??
Here is a version of a Rider of Rohan.The new cavalry harness from 4868 set is amazing, the detail is beautiful.
...- Theoden? I really like him and the wooden shield. ...
As for giving all factions of middle earth different helms,I don't think that is strictly necessary.
No, Theoden has golden armor, much closer to Plate.
...Actually the armour of the already mentioned 4810 rondorian would do the job here.
