Really nice style! I just don't know if the other eyebrow should be visible when lips suggest this to be a profile picture, maybe that I'm wrong! and yes.. as someone already mentioned the ear seems to be too far from the face and too low! But the rest is pure beauty ^^
Beautiful work, even for a rough. Captures the feeling very well. I don't know if you were going for a more cartoon atmosphere here, or a more realistic one, but it seems to me the ear is too far down and too far back on the head. Otherwise I would say excellent work!
