That's a personnal basic concept I made for a new unit which will be playabe in my Minas Tirith maps (in An Edain Submod). Keep in mind that "concept" mean that some things will be changed (colors, details, some elements could even be removed and used for another unit ...). The real goal of this is to feel how will look the unit in globality before to start the 3D making.
For the story, they are the personal guard of king Elessar Telcontar (Aragorn), keepers of the Throne of Gondor. You can find more information about their story here if you are interested : Wetanz.com
More to come...
Original White Tree of Gondor that I modified : Flickr.com
How beautiful it looks I love the ridges
It would be interesting with a mouth cap
Thank you for advise, I can try that as a variation :)
