Orginally intended for the selout challenge here...Posted it when I was working on it orignally over at Pixelation and got a significant education in outline concepts and techniques.

Nice, and the thread is interesting (especially to see the progress of your work). :)
However... I don't know, the tail and arms looks shaded differently from the rest. Either they're not detailled enough, or the clothes and hairs are too detailled. May I asked why you get rid of the rings ? (hope that's the same word in french and english, because I have no idea how to say that XD)
The face (and whole head) is super nice, tho. :)
