Ed's second recoloring would go much better with much of the clothing, but now, I really see the shield in a different light.
Padren, stop calling me Spike.

I resent this account already. 'Argo' or 'Argosax', we aren't the best of buddies, got we are acquainted, so use my name.
I do agree, Dustari is a Knight/Caviller kingdom, based mostly on a more, medi-eval style of ranks and RP. So, I think maybe the shield should have 2 variations now.
One for the Knight, the current shields colors actually look rather fine, just took some getting used too, but add a simple negative to it to balance it.
The Cavaliers can be a high AC one, since a strong Lance leaves a Calavlier vunerable, or perhaps just re-color this one, and event it off as a... Calavlier shield.
I don't know really though, alot of good ideas in my mind, just, I'm unable to make anything of them.
