You know when you get to the end of a drawing and you're not sure if it's finished or not?? No? No, I suppose you don't, but that's where I am with this piece. And I've had a gutsful of staring at this unknown eye for months on end. I will put it away and take another look in a month or so and see if any touching up is required. Quite satisfied overall, but the skin below the eye has proved to be very difficult to render.
