Update: Here is a more recent rendition of Arthur: [link]. There are still certain things about this one that I prefer, but it is fun to look back and see how far I've come.
I love how simple Excalibur looks: not prettied up with weird shapes or anything. It's just a simple, extraodinarily powerful blade. His missing scabbard is a nice touch too, which means this would have been him after Morgana stole the sheath?
Love the Surcoat
In regard to the arms, historically the golden lions on a red field have been used with the English kings of the house of Plantagenet after Henry II.
Arthur has been seen and described with anywhere from three to thirteen crowns on either a red or blue backing, representing his numerous domains, which include areas in France. As for the fleur-de-lys, TH White's The Once and Future King describes Arthur's father Uther as a kind of William the Conqueror figure, and Merlin frequently describes the nobility as Norman. National borders weren't as clear cut as they are today, at least not until later in the Middle Ages : )
The dragon rampant would be his father's coat of arms, while I threw in the castle and the cross to represent Camelot and his piety, or to signify the grail quest.
Thanks for bringing up the coat-of-arms, I love discussing details like that!
And I spent a lot on those Hitmen. >.>
But seriously, I haven't seen any updates from you in a while. It's good to see you back.
