Possibly your best work, Flaber. The hair is great, and the metal armor works brilliantly. I think the dithering, in parts, adds unneccessary texture to the facial features. I also don't like the back side of the next, looks really pillowy, and somewhat blurry. I'd also darken the outline of the hair bows a tad. Additionally, I'd also check the anatomy of that ear- it looks a bit small and misplaced.

I haven't seen the original lines, but youve certainly made something beautiful here with the colouring.
