Very nice flavor on knight and myth, also love the art.
One note: The knight's armor doesn't work as described, I think. He has three pieces of chest armor, but only two of those stack, plate and either gambeson or mail. But on the other hand, you could also see this as the Circle Knight carrying around an extra piece of armor to either gift his company or to give inferior foes before a duel to make things more fair or something. Other than that, he's pretty cool and interesting!
