Thanks for all the compliments guys! Of course, after 25 years of painting miniatures, I would hope they would come out good!

As far as the leader knight goes, he was inspired by some Warhammer Online concept art. I saw the small griffon from the building set (which is also where the banner head came from too), and knew I could make a killer helmet decoration from it. I also added some wings from the High Elf Lord sprue, and even some bits from a space marine sprue (the canvas shoulder decoration, what I like to call "The Pledge of Myrmidia).
My thoughts on the Bretonnian horses were two-fold. One is I just love painting banners, and horse caparisons offer the same opportunities for flare that banners do. Second; I felt that Some of the Knights may have either come from Estalia, or made a Pilgrimage there to worship Myrmidia, so they could have acquired them in their travels through Bretonnia. Though now I wish I had done a little more work to make them a little more armored, and Empire-ish.
All-in-all I really was very pleased how they came out (and how well they have performed thus far in battle... they have crushed units of Chaos Knights, Warriors, and Bloodletters, and even may claim to have felled a Lord of Change)! For the last few years I have strived to make every miniature in my army an individual, and love the way it looks when they are each different, and these are no different.
Actually, I need to take some photos of my Battle Priest of Myrmidia (I am very proud of her). I'll post them as soon as I can.
Thanks again everyone!
