Those Brettonians are great!

Plus, all the different heraldry of the lords looks great, very Bretonnian, and its a nice contrast to the neutral colours of the infantry's armor.
My thought exactly! The Bretonians are a very diverse army, in terms of appearance. And I wouldn´t tone down the shields too much, the coat of arms is, after all, their lord´s pride, and he´d be eager to show it off.

Hm, I´m looking forward to the Bretonian Knights. And the Imperial ones, too.
