I had wondered why you hadn't posted anything up lately... :wink:
Continuing to improve, I see. In general the pose is very strong, especially the dropped right shoulder, though you are right about the boots. They just don't seem 3D somehow.
My only other criticism is that the eyes aren't quite level. Since the eyes are the soul of the picture, it's important to get them right. Drawing in really faint guidelines to indiceate the angle of the face might be a good idea here.
So, you tried inking anything yet?
