I've spent about 20 hours or so on this, I can easily spend another 20-50. There are a bunch of issues and I've tried to fix them, but every time I look I find a bunch more. When do you move on? I think maybe my base drawing may not have been sufficiently secured or my painting skills aren't quite up to fixing the errors.
I've tried to move into attempting to find the basic shapes (little cylinders for the hair, spheres for the eyes, the wedge of the nose, etc) and make rendering decisions based on that and I think I'm improving in that area.
Crits definitely welcome.
