Rohirric Celtic Horses

I was thinking about Rohan one day, as I all too often do. And about the correspondence that Tolkien saw between the Rohirric culture and the Anglo-Saxon cultures, and the way Alan Lee depicted the Rohirrin sets as very Celtic styled. Then I came across something called the Aberlemno Stone, which showed 2 sea-horses intertwined, and reminded me awfully of Rohan. So this is based a little on the Aberlemno Stone, and is an attempt at creating some form of Rohirric design.
