I was reading the comments (looking for an amusing caption X3) and I saw the whole armor thing; I'd just like to say that certain OLD old-school ponies (royals/alicorns, I believe) had those same "accessories" (the fleur-de-lis hoof marks/"hoof covers", among other things) and I always assumed it was inspired by that, as all current MLP designs are loosely based off of pre-existing ponies. There are new things as well, such as Nightmare Moon, but I don't think the armor theory is entirely accurate (no offense intended).

I think i made my life's most fatal mistake while watching 2 first episodes of this series, because i immediatedly fell for both Celestia and Luna, and i really, really like this picture, the poses, the faces, they're incredible, love it ^^.
Luna: Um, Cellie? Remember that time when I was Nightmare Moon... Cellie: Yup... uh-huh...
