I love the greyscale style with a splash of color, you see it rarely by artists but it's ALWAYS so COOL! also, I only just realized there isn't guidline marks or messy lines or anything in your work what is the secret of perfection!?!
This made me think of Eddard "Ned" Stark from the Game of Thrones series...I saw this and got the image of Twilight saying "Winter is coming..." with the same epic serious face she has here. Great job, btw! The armor and sword are very well-done, and she's even kinda sexy in a way.
